SGM8545XN5 from SGMICRO, 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	Amplifier output. Rail-to-rail output swing; typical VOH = 4.997V and VOL = 5mV with RL = 100kΩ at VS = 5V. Sources up to 84mA and sinks up to 75mA typical.
2	+VS	power_in	Positive supply pin. Operating range 2.1V to 5.5V (absolute maximum 6V between +VS and -VS). Bypass to ground with a local decoupling capacitor.
3	+IN	input	Non-inverting input. Rail-to-rail input common-mode range from (-VS − 0.1V) to (+VS + 0.6V), i.e. -0.1V to +5.6V at VS = 5.5V. Input bias current typically 0.5pA.
4	-IN	input	Inverting input. Same rail-to-rail common-mode range as +IN (-0.1V to +5.6V at VS = 5.5V). Input bias current typically 0.5pA.
5	-VS	power_in	Negative supply / ground pin. Tied to GND in single-supply applications. Absolute maximum 6V between +VS and -VS.
