A simple variable power supply circuit with L200

simple power supply L200 circuit diagramVariable power Supply scheme shown here is very simple, its used regulator IC L200 (ADJUSTABLE VOLTAGE AND CURRENT REGULATOR). L200 is a monolitthic IC for current and voltage programmable regulation. It has current limiting, power limiting, thermal shutdown, and over voltage protection.

Variable power supply based L200 for its output voltage is controlled by a variable resistor 10K. Output voltage range of values ​​is from around 3 to 15 volts, and current range is about 10 mA minimum and a maximum of 2 amps. Exceeding current limit will reduce the output voltage to zero.

Variable power supplyParts list :
Resistors : 1 K, variable resistor : 10K, 47R
Capacitors : 4700 uF/ 16 V, 100nF (2), 10uF/16V
Regulator IC : L200
Transformer : 12 volt 2 Ampere
Fuse : 1 A

 

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
