Regulator Power Supply 1A Circuit Schematic

Small power supply that provides a regulated voltage, adjustable between 1.5 and 35 volts at 1 ampere. This schema is ready to use, you just need to add a suitable transformer. This schema is thermal overload protected because the current limiter and thermal overload protection are included in the IC.

This is the Regulator Power Supply 1A Part List :

IC = LM317
P1 = 4.7K
R1 = 120R
C1 = 100nF - 63V
C2 = 1uF - 35V
C3 = 10uF - 35V
C4 = 2200uF - 35V
D1-D4 = 1N4007
