IL2931 SERIES

LOW DROPOUT VOLTAGE REGULATORS

The LM2931 series consists of positive fixed and

TO-226AA /

adjust-

TO-92

able output voltage regulators that are specifically designed to maintain

proper regulation with an extremely low input-to-output voltage

differential. These devices are capable of supplying output currents in

excess of 100 mA and feature a low bias current of 0.4 mA at 10 mA

output.

3.Input

Designed primarily to survive in the harsh automotive

environment, these devices will protect all external load circuitry from

battery jump starts, and excessive line transients during load dump.

This series also includes internal current limiting, thermal shutdown,

and additionally, is able to withstand temporary power-up with mirror-

image insertion.

TO-220 AB

Due to the low dropout voltage and bias current specifications,

the LM2931 series is ideally suited for battery powered industrial and

consumer equipment where an extension of useful battery life is

desirable. The ‘C’ suffix adjustable output regulators feature an output

inhibit pin which is extremely useful in microprocessor-based systems.
