IL2931 XX

TECHNICAL DATA
LOW DROPOUT VOLTAGE REGULATORS
IL2931-5.0
The IL2931 series consists of positive fixed and adjust-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.
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.
Due to the low dropout voltage and bias current specifications, the
IL2931 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.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
