1.2 V to 5.5 V Input Voltage Operating Range
Typical RON
The FPF1203 / 03L / 04 / 45 are ultra-small integrated
IntelliMAX™ load sw itches w ith integrated P-channel
sw itch and analog control features. Integrated slew -
rate control prevents inrush current and the resulting
excessive voltage drop on the pow er rail. The input
voltage range operates from 1.2 V to 5.5 V to provide
pow er-disconnect capability for post-regulated pow er
rails in portable and consumer products. The low shut-
off current allow s pow er designs to meet standby and
off-pow er drain specifications.

The FPF120x are controlled by a logic input (ON pin)
compatible w ith standard CMOS GPIO circuitry found
on Field Programmable Gate Array (FPGA) embedded
processors. The FPF120x are available in 0.76 mm x
0.76 mm 4-bump WLCSP.
