TC1017-2.5VLTTR from Microchip Tech, 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	SHDN	input	Shutdown control input: regulator is fully enabled with logic-high (VIH min 45% of VIN) and shut down with logic-low (VIL max 15% of VIN), dropping supply current to 0.05 µA typ.
2	NC	unconnected	No connect.
3	GND	power_in	Ground terminal, recommended to be tied to a ground plane for best performance.
4	VOUT	power_out	Regulated voltage output, rated 150 mA, to be bypassed to GND with a minimum 1 µF capacitor (ceramic recommended).
5	VIN	power_in	Unregulated supply input, 2.7V to 6.0V operating range, recommended to be bypassed to GND with a ceramic capacitor.
