Laboratory Power supply lm317 1.2 - 36 volt and current limiter 0 - 5 amps



The schematic for the lm317 based powersupply includes two PNP transistors to increase the power performance.

There is a fault on this schematic, the bd140 current limiter is connected wrong, i will make a new schematic latter.

You can make a shortcut protection circuit for this power supply also follow link

  1. The series 12Volt 35 Amp Power Supply is very simple, because the voltage regulators make use of IC7812 which will leave a power regulator alone. mil power source
