Its 18.3 mOhm typical on-resistance sets the voltage drop at 36.6 mV when carrying the full 2 A rated output — a conduction loss of roughly 73 mW at that point, which is manageable without a heatsink in most PCB layouts. The switch operates from a 0.75 V to 3.6 V load voltage range, covering the common 1.2 V, 1.8 V, and 3.3 V digital rails. No separate Vcc/Vdd supply is required — the part is self-biased from the load voltage.
The slew-rate-controlled turn-on limits inrush current into the output capacitor, which reduces the risk of a voltage dip on the input rail during power-up. The load discharge feature pulls the output to ground through an internal resistor when the switch is disabled, preventing an indeterminate output state that could leave downstream logic inputs floating. The On/Off interface accepts a non-inverting logic signal, so a logic-high enables the switch. This simplifies the enable connection to a GPIO or a power-good signal from a preceding regulator.
The 0.89 mm width means the part fits into tight component keep-out zones near board edges.
