Description

Circuit schematic like in Figure 1 above is Circuit Schematic Variable Power Supply using LM317. Eleccircuit site describe that Sometimes we need to use 1.5V power supply circuit but we cannot normmally use IC-7805. Or we need to use other voltage e.g. 13V or 4.5V. Best way we need the Variable Regulated power supply. We are beginner and easest we use LM317 (3 terminal positive adjustable regulator).

The LM317 is a adjustable regulator IC that designed to many supply for 1.5A output and adjustable over 1.2V to 37V, and with current limiting, thermal shutdown, full protection. This circuit is design for you. It can supply voltage 1.2V to 30V at all range is 1A.

And now you can read more you knowledge about Circuit Schematic Variable Power Supply using LM317 from the original source article using link [here].
