Description

The IFX25001 is a low dropout linear voltage regulator available in a 2.5, 3.3, 5.0, 8.5, or 10.0 V output. It is

capable of supplying continuous output current up to 400 mA. A wide input voltage range up to 45V enables the

IFX25001 to operate in a large variety of applications. The IFX25001 is also protected against overload, short

circuit and overtemperature conditions.
