Delayed activation 15V voltage source using LM317.
This circuit uses the LM317 voltage regulator. This voltage source also uses a bipolar PNP transistor and an electrolytic capacitor, to achieve a delayed activation of the voltage regulator
This 20 Amp Variable Power Supply varies its output voltage from 1.5 to 15 volts and is based on the well-known variable voltage source configuration, where only the LM317 voltage regulator is used.
