TPS22942DCKR from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VOUT	output	Switch output; place ceramic bypass capacitor(s) between this terminal and GND.
2	GND	power_in	Ground reference for the device; place bypass capacitors between VIN or VOUT and this terminal.
3	OC	output	Active-low, open-drain over-current flag that indicates an over current, supply undervoltage, or over temperature state.
4	ON	input	Switch control input that must not be left floating.
5	VIN	power_in	Switch input; place ceramic bypass capacitor(s) between this terminal and GND.
