L4941_06 Datasheet, PDF (1/17 Pages) STMicroelectronics – Very low drop 1A regulator

L4941
Very low drop 1A regulator
Feature summary
■ Low dropout voltage (450mV typ. at 1A)
■ Very low quiescent current
■ Thermal shutdown
■ Short circuit protection
■ Reverse polarity protection
Description
The L4941 is a three terminal 5V positive
regulators available in TO-220 and DPAK
packages, making it useful in a wide range of
industrial and consumer applications. Thanks to
its very low input/output voltage drop, these
devices are particularly suitable for battery
powered equipments, reducing consumption and
TO-220
DPAK
prolonging battery life. It employs internal current
limiting, antisaturation circuit, thermal shut-down
and safe area protection.
