I want mini size switching regulator,so it input voltage 9V to 3V Step-Down Converter circuit.
The LM2574 series of regulator are monolithic integrated circuits that provide all the active functions for a step down (buck) switching regulator, capable of driving a 0.5A load with excellent line and load regulation.
The LM2587 series of regulators are monolithic integrated circuits specifically designed for flyback, step-up (boost), and forward converter applications.
The transformer T1 steps down mains voltage, to 12rms & the rectifier bridge D1 rectifies it to produce a DC voltage. By changing the value of the Zener diode, different output voltages can be obtained from the circuit. 1) how much maximum output(voltage and current) can stepper motor (of Dot matrix printer)gives if we run it with some driving device.
September 5, 2015 By Administrator 5 Comments A regulated power supply is very much essential for several electronic devices due to the semiconductor material employed in them have a fixed rate of current as well as voltage. As we have previously talked about that regulated power supply is a device that mechanized on DC voltages and also it can uphold its output accurately at a fixed voltage all the timeA  although if there is a significant alteration in the DC input voltage.
ICs regulator is mainly used in the circuit to maintain the exact voltage which is followed by the power supply. A circuit diagram having regulator IC and all the above discussed components arrangement revealed in the figure below. C1This capacitor is known as bypass capacitor and is employed to bypass extremely tiny duration spikes to the ground with no distress the other components. C2C2 is the filter capacitor employed to steady the slow changes in the voltage applied at the input of the circuit.
C3C3 is known as a filter capacitor employed in the circuit to steady the slow alterations in the output voltage. C4C4 is known as bypass capacitor and worked to bypass very small period spikes to the earth with no influence the other components. As we have made the whole circuit till now to be operated on the 5V DC supply, so we have to use an IC regulator for 5V DC.
In the circuit diagram C2 as well as C3 are filter capacitor while bypass capacitors are the C1 and C4.The electrolytic polarized capacitors are employed for this purpose. Currently we have the circuit for the 5V DC positive regulation and we are also familiar with the component values used in the circuit. This is a basic universal variable Power Supply voltage regulator circuit using an LM317, 3-terminal regulator in a TO-220package. When external capacitors are used with any IC regulator it is good practice to add protection diodes to prevent the capacitors discharging back into the regulator in the event of abnormal operating conditions, like a sudden short circuit on the input or the output, or a back emf from an inductive load. Build your own Accurate LC Meter (Capacitance Inductance Meter) and start making your own coils and inductors. 1Hz - 2MHz XR2206 Function Generator produces high quality sine, square and triangle waveforms of high-stability and accuracy. Having the ability to control various appliances inside or outside of your house wirelessly is a huge convenience, and can make your life much easier and fun.

Click here for the comprehensive LT1073 Specification Sheet which includes many example circuits using this chip. The circuit can be employed on occasions when a current of more that 3A is demanded for regulator. A regulator is mainly employed with the capacitor connected in parallel to the input terminal and the output terminal of the IC regulator. Escalating the value of the capacitor amplify the stabilization as well as the declining value of the capacitor reduces the stabilization.
Raising the value of the capacitor enlarges the stabilization furthermore declining the value of the capacitor declined the stabilization. And the most generally used IC regulators get into the market for 5V DC regulation use is 7805. This IC is very flexible and is widely employed in all types of circuit like a voltage regulator.
In the table below we have mentioned the value in detail of all the components used in the circuit of 5V DC positive regulator.
The Universal Power Supply output voltage can be set to anywhere in the range 1.5V to 30V by selecting two resistances.
This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.
It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc.
BA1404 HI-FI Stereo FM Transmitter broadcasts high quality stereo signal in 88MHz - 108MHz FM band. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.
8-DIP machined IC socket allows to swap OPA2134 with many other dual opamp chips such as OPA2132, OPA2227, OPA2228, dual OPA132, OPA627, etc. It's breadboard compatible so it can be plugged into a breadboard for quick prototyping, and it has VCC & GND power pins available on both sides of PCB. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.

Import charges previously quoted are subject to change if you increase you maximum bid amount.
I use IC 555 ( hot ic Timer) for Squarewave Oscillator to Driver mini Transformer and Diode, Zener Diode to Out DC Voltage. For the checking of gigantic alterations in the input as well as in the output filter, capacitors are used.
By this circuit can give Voltage go out about 12V, depend on Zener diode or ZD1 usual use 12V values thus.
By using a potentiometer, R2, as one of the resistors you can dial up the output voltage wanted. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.
Unlike other ESR Meters that only measure ESR value this one measures capacitor's ESR value as well as its capacitance all at the same time. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery.


It's small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. By the help of a voltage regulator DC, unregulated output will be fixed to a constant voltage. While the bypass capacitors are used to check the small period spikes on the input and output level.
If D5 is not presented in the circuit, the output capacitor can leave its charge A immediately during low impedance course inside A the regulators.
The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. In operation above 1Amp load current the voltage started dropping hence I added a CL100 (Any medium power high gain NPN transistor will do) as darlington to 2N3055. The circuit is made up of linear voltage regulator 7805 along with capacitors and resistors with bridge rectifier made up from diodes. Bypass capacitors are mainly of small values that are used to bypass the small period pulses straightly into the Earth.
To be safe for continuous operation the maximun input DC voltage to the regulator should not be over 33V.
USB IO Board is self-powered by USB port and can provide up to 500mA for electronic projects. Board features 28-PIN DIP IC socket, user replaceable ATmega328 microcontroller flashed with Arduino bootloader, 16MHz crystal resonator and a reset switch.
That is the zener voltage minus base emitter voltage of Q1.Here transistor Q1 will conduct the excess current required .
From giving an unchanging voltage supply to building confident that output reaches uninterrupted to the appliance, the diodes along with capacitors handle elevated efficient signal conveyal.
Whatever current flows through R1 also flows through R2, and the sum of the voltage drops across R1 and R2 is the output voltage. SO Will you plz provide me with the necessary schematics so that I can adjust the voltage and current.
The input DC voltage to the regulator must be at least 2.5V above the required output voltage.
