GT8051S5 from GTIC, 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. Class-AB rail-to-rail output stage; swings within ~20 mV of the supply rails with high-impedance loads. Typical output current source 160 mA, sink 110 mA.
2	V-	power_in	Negative (lowest) power supply. Connect to ground for single-supply operation or to the negative rail for dual-supply. Total supply range VS = (V+) - (V-) is 2.5 V to 5.5 V.
3	+IN	input	Positive (non-inverting) input. Common-mode range extends beyond the supplies (-0.3 V to 3.6 V at VCC=5 V). Input bias current typically ±1 pA.
4	-IN	input	Negative (inverting) input. Common-mode range extends beyond the supplies. Diode-clamped to the supply rails; limit currents to <10 mA when signals exceed rails by >0.3 V.
5	V+	power_in	Positive (highest) power supply. 2.5 V to 5.5 V single supply (or up to ±2.75 V dual). Decouple with a local ceramic capacitor close to the pin.
