HLP5907MFX-3.3 from HXY MOSFET HLP5907MFX 3 3 NOPB, in a SOT-23-5L. 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	Power supply input. Accepts up to 6V absolute maximum; requires input capacitor (1uF-10uF typical, 10uF in typical application circuit).
2	GND	power_in	Ground reference (labeled GDN in the datasheet table, corresponds to VSS in the functional block diagram and application circuit).
3	CE	input	Chip Enable input. Drive high to enable the regulator; drive low (Vce=0V) to shut down the output. Shutdown current is typically 0.1uA (max 1uA).
4	NC	unconnected	No connection. Leave floating (悬空).
5	VOUT	power_out	Regulated power output. Fixed 3.3V (per '-3.3' suffix), 300mA maximum output current. Requires output capacitor (1uF-10uF typical, 10uF in typical application circuit).
