# TSB571ILT

**STMicroelectronics** · Operational Amplifier · SOT-23-5

TSB571ILT 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 | OUT | output | Amplifier output channel (rail-to-rail output). |
| 2 | VCC- | power_in | Negative supply voltage; supply range 4 V to 36 V between VCC+ and VCC-. |
| 3 | IN+ | input | Non-inverting input channel; rail-to-rail, common mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V, input current limited to 10 mA. |
| 4 | IN- | input | Inverting input channel; rail-to-rail, common mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V, input current limited to 10 mA. |
| 5 | VCC+ | power_in | Positive supply voltage; operating 4 V to 36 V, absolute maximum 40 V, 22 nF decoupling capacitor recommended close to the pin. |
