TS1871ILT 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 | Rail-to-rail amplifier output, swinging within 100 mV of each rail with a 600 Ω load and typically sourcing 65 mA. |
| 2 | VCC- | power_in | Negative supply (ground) terminal; supply range VCC is 1.8 to 6 V between VCC+ and VCC-. |
| 3 | In+ | input | Non-inverting input, with common-mode range extending 0.2 V beyond each supply at 25 °C and absolute maximum input voltage of VCC- -0.3 V to VCC+ +0.3 V. |
| 4 | In- | input | Inverting input, with common-mode range extending 0.2 V beyond each supply at 25 °C and differential input voltage limited to ±1 V. |
| 5 | VCC+ | power_in | Positive supply terminal; operating range 1.8 to 6 V and absolute maximum supply voltage 7 V. |
