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.

Note: Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are
not designed for continuous repetitive operation.
