5V / 4A Regulator Circuit

5 V 4 A regulator

This is the other power supply regulator circuit, is different from the previous circuit, this using IC op amp quad type MC 3401 operational amplifier from Motorola. Here is also used NPN Epitaxial Silicon Darlington Transistor MJE 800.

This circuit can provide current up to 4A at a 5V.

VO- VZ + 0.6 Vdc
NOTE  :

  • R is used to bias the zener
  • if the Zener TC is positive, and equal in magnitude to the negative TC of the inputto the operational amplifier    (> 2 0 mV/°C). the output is zero. TC A 7 0 Volt Zener will give approximately zero TC

 


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.
