TPS22949 Datasheet (Texas Instruments) - Current-Limited Load Switch

TPS22949, Current-Limited Load Switch

The TPS22949 and TPS22949A are devices that provide protection to systems and loads in highcurrent conditions.

The device contains a 500-mΩ current-limited P-channel MOSFET that can operate over an input voltage range of 1.62 V to 4.5 V as well as a low-dropout (LDO) regulator with a fixed output vo
