HGV333M5 from HGSEMI, 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	OUT	output	Op-amp output. Rail-to-rail output stage capable of swinging close to V+ and V-.
2	V-	power_in	Negative supply rail (lowest potential). For single-supply operation tie to GND; for split-supply operation connect to the negative rail. Total supply range 1.8 V to 5.5 V between V+ and V-.
3	+IN	input	Non-inverting op-amp input. Rail-to-rail common-mode range including both supply rails; internal EMI filter on this pin.
4	-IN	input	Inverting op-amp input. Rail-to-rail common-mode range; internal EMI filter on this pin.
5	V+	power_in	Positive supply rail (highest potential). 1.8 V to 5.5 V single-supply range referenced to V-. Bypass with a local 0.1 µF ceramic to V-.
