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.

2.Ground
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.
• Input-to-Output Voltage Differential of Less Then 0.6 V at 100mA
• Output Current in Excess of 100 mA
