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 lowvoltage control signals. A 120-Ω on-chip load resistor is added for output quick discharge when the switch is turned off. TP...
