LM2931, NCV2931 Series

100 mA, Adjustable Output,

LDO Voltage Regulator with

60 V Load Dump Protection

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.

these devices will protect all external load circuitry from input fault

conditions caused by reverse battery connection, two 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.

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.
