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.
