transportation applications. For automotive applications please refer to
the Infineon TLx (TLE, TLS, TLF.....) voltage regulator products.
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. In addition the device can be switched off via the Enable input which reduces the current consumption
to less than 10 μA.
