LM78L12AC Datasheet 3-terminal Positive Regulators

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM78LXX Series 3-Terminal Positive Regulators May 2003 LM78LXX Series 3-Terminal Positive Regulators.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LM78LXX series of three terminal positive regulators is available with several fixed output voltages making them useful in a wide range of applications.

When used as a zener diode/resistor combination replacement, the LM78LXX usually results in an effective output impedance improvement of two orders of magnitude, and lower quiescent current.

These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regulation.
