HT7350 from GUOXIN JIAPIN SEMICONDUCTOR, in a SOT-23-3L. 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	Chip ground reference (芯片接地端). Common return for input and output. Connect to system ground with a low-impedance path close to the input/output bypass capacitor return.
2	VIN	power_in	Unregulated input supply (启动输入端). Operating range for HT7350 is 6 V ≤ VIN ≤ 12 V for full regulation; absolute maximum input voltage is 15 V. Bypass with a 10 µF capacitor (C1) to GND close to the pin.
3	VOUT	power_out	Regulated output (芯片输出端). Nominal 5.0 V ±3% (4.85 V min / 5.15 V max) with dropout ~60 mV at 40 mA. Rated output current 250 mA (VIN=6 V, VOUT≥4.5 V), typical operating current 40 mA. Requires a 10 µF output capacitor (C2) to GND for stability.
