Description

The IFX25401 is a monolithic integrated low dropout voltage regulator for load currents up to 400 mA. An input

voltage up to 40 V is regulated to an adjustable voltage with a precision of

±2%. The device is designed for harsh

environments. Therefore it is protected against overload, short circuit and overtemperature conditions by the

implemented output current limitation and the overtemperature shutdown circuit. The adustable output can be

configured to regulate between 2.5 V and 20 V.

Due to its very low quiescent current the IFX25401 is dedicated for use in applications permanently connected to

a battery.
