Build a 1.2-36V 5A Adjustable Power Supply circuit diagram with LM317. This circuit is a simple power supply circuit. 1.2 - 36V adjustable bench power supply with 5A of
output current. Max input voltage is 37V and output is adjustable via
potentiometer between 1.2 up to 36 volts. TIP147 PNP darlington
transistor boosts the current of LM317 from 100mA to 5A. LM317 is the
most useful and inexpensive adjustable regulator and for this circuit
you can also use LM317 L that can give 100mA, that's enough for
transistor bias.

D1 and D2 are protection diodes because when you turn
the circuit off the output capacitors are discharging and can damage the
transistor or regulator. 100nf capacitors are in parallel with
electrolytic capacitors to remove high frequency noise because large
value electrolytic have large ESR and ESL and can't remove high
frequency noise.
