TECHNICAL DATA
LOW DROPOUT VOLTAGE REGULATORS ^IL2931AZ-5
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.
