The FPF1203 / 04 / 45 are ultra-small integrated IntelliMAX™ load switches with integrated P-channel switch and analog control features. Integrated slew-rate control prevents inrush current and the resulting excessive voltage drop on the power rail.

The input voltage range operates from 1.2V to 5.5V to provide power-disconnect capability for post-regulated power rails in portable and consumer products. The low shut-off current of 1µA (maximum) allows power designs to meet standby and off-power drain specifications.
