DESCRIPTION

The UTC  US2236108DB  is an ultra-small, low ON-state

resistance (RON) load switch with controlled turn on. The device

contains a P-channel MOSFET  that operates over an input

voltage range of 1.0 V to 3.6 V.  The switch is controlled by an

on/off input (ON), which is capable  of interfacing directly with

low-voltage control signals. A 120-Ω on-chip load resistor is

added for output quick discharge when the switch is turned off.
