Variable Regulated Power Supply Circuit Diagram Using Lm317

However make sure that all the 2n3055 are mounted over a large common heatsink using a generous amount of heatsink compound paste but without mica isolators.

Variable regulated power supply circuit diagram using lm317.

The lm317 is a 3 terminal positive voltage regulator with a 1 25 to 37 volts output voltage range. Complete circuit diagram variable power supply using lm317. With a small circuitry attached with lm317 we can get variable voltage up to 37v with 1 5a max current. But what if need to vary the power supply voltage so here we have variable voltage regulator ic lm317.

How to use lm317 for producing a variable output. The project shown here is a schematic of lm317 5a variable or adjustable power supply circuit. The lm317 regulator terminals are. This ic is normally available in to 220 package and.

Lm317 variable voltage regulator circuit lm117 lm217 lm317 variable voltage regulator characteristics. With the advent of chips or ics like lm317 l200 lm338 lm723 configuring power supply circuits with variable voltage output with the above exceptional qualities has become very easy nowadays. Lm317t is a very famous voltage regulator ic mostly used in many types of power supply circuits and battery charger circuits it is available in to 220 transistor package in the market. In input out output adj adjust.

The capacitance c3 bypassing the adjust pin to ground will improve the ripple rejection capability while the diodes are used to protect the regulator from excess flowing through it if a battery or any other voltage source is connected across the output terminals of the regulator.
