LM123A - 5-Volt Positive Regulator

Download the LM123A datasheet PDF. This datasheet also covers the LM123 variant, as both devices belong to the same 5-volt positive regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM123 is a three-terminal positive regulator with a preset 5V output and a load driving capability of 3 amps.

New circuit design and processing techniques are used to provide the high output current without sacrificing the regulation characteristics of lower current devices.
