3A Switching Voltage Regulator based LM317HV circuit

Above circuit diagram is a easy, simple and cheap switching voltage regulator which has capability to deliver adjustable voltage output range of 1.8V to 32V and static electric current of 3A. This regulator use adjustable regulator IC of LM317HV and a power PNP transistor of 2N3792.

The LM317HV is adjustable 3-terminal positive voltage regulators capable of supplying in excess of 1.5A over a 1.2V to 57V output range.

Circuit Notes:

C1 and C4 must be solid tantalum capacitor type to get the best output quality.L1: CORE-ARNOLD A.254168.2 60 TURNS
