H7530-1 from Shanghai Siproin Microelectronics, in a SOT-23. 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	GND	power_in	Device ground / common return. Tie to the single-point GND of the input and output bypass capacitors (10μF typical on both VIN and VOUT).
2	VOUT	power_out	Regulated 3.0V output (2.94V-3.06V, ±2%). Delivers up to 150mA (120mA min guaranteed) with a typical 50mV dropout at 1mA. Requires a 10μF output capacitor for stability.
3	VIN	power_in	Unregulated supply input. Recommended operating range 4V ≤ VIN ≤ 15V (16V used in line-regulation spec); absolute max 18V (−0.3V to +18V). 10μF input bypass capacitor recommended.
