Most complete introduction to LM337 you can find nowhere!

This blog describes LM337 pinout, circuit, equivalent, features, where and how to use this ic and other important details.

Too tired to look up the datasheet for the component parameter?

 Wonder where this ic can be used?

 Worried about wrong input/output voltage might ruin your whole project?

Having this detailed but not complicated introduction/instruction in your hand, all those questions can be solved!

Easy to Build Adjustable Dual-Rail PSU

Adjustable dual-rail power supply is an essential utility for analog electronic experiments. In this post we illustrate extremely simple, adjustable dual-rail power supply using LM317 and LM337 voltage regulators ICs. This PSU delivers 2A ±1.35V to ±18.5V output and thanks to 3 turn linear potentiometers output can be adjustable up to 2nd decimal point.

The PCB of the PSU is simple to design and compact (65mm × 50mm). Both LM317 and LM337 need at least 60mm × 55mm or larger heat sinks (and both of these heat sinks need to be electrically isolated). The PCB and schematic of this PSU is available to download at here.
