RT9013-15GB from Richtek Tech, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VIN	power_in	Supply input, 2.2V to 5.5V operating range (absolute max 6V). Bypass with a 1µF ceramic (X7R) capacitor to GND.
2	GND	power_in	Common ground reference for the regulator.
3	EN	input	Enable input, active high (VIH ≥ 1.6V, VIL ≤ 0.6V, IEN ≈ 0.1µA). Driving EN low places the device in shutdown mode (typ 0.7µA). TTL-logic compatible; do not leave floating (use a pull-down such as 100kΩ if unused).
4	NC	unconnected	No internal connection.
5	VOUT	power_out	Regulator output, fixed 1.5V (±2% accuracy at IOUT=10mA), 500mA capable. Requires a 1µF ceramic (X7R) output capacitor to GND for stability.
