TS321IYLT from STMicroelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Output output Op amp output, sources about 40 mA typ and sinks 20 mA typ at VCC+ = 15 V, short-circuit to ground 40 to 60 mA.
2 VCC- power_in Negative supply, ground in single-supply operation (dual supplies ±1.5 to ±15 V).
3 Non-inverting input input Non-inverting input, common mode range 0 to (VCC+) - 1.5 V at 25 °C and includes ground.
4 Inverting input input Inverting input, common mode range 0 to (VCC+) - 1.5 V at 25 °C, differential input voltage up to ±32 V.
5 VCC+ power_in Positive supply, 3 to 30 V operating range (absolute maximum 32 V).
