HXV8541DBVRG from HANSCHIP semiconductor, 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 A	output	Amplifier A output. Rail-to-rail output stage capable of sourcing/sinking ~15 mA (typ) at VS=2.7 V; short-circuit current ±20 mA typ.
2	V-	power_in	Negative supply / ground rail. Typically tied to GND for single-supply operation; total supply span V+ to V- must not exceed 6 V absolute maximum.
3	+IN A	input	Non-inverting input of amplifier A. Rail-to-rail common-mode input range from V- to V+; input bias current typ 4 pA.
4	-IN A	input	Inverting input of amplifier A. Rail-to-rail common-mode input range; differential input voltage limited to ±6 V absolute maximum.
5	V+	power_in	Positive supply pin. Single-supply range 2.7 V to 5.5 V (6 V absolute max relative to V-). Bypass locally with a 0.1 µF ceramic capacitor to V-.
