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

TSB621ILT 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 output capable of sourcing/sinking 35-45 mA at VCC = 36 V. |
| 2 | VCC- | power_in | Negative supply voltage reference for 2.7-36 V operation. |
| 3 | IN+ | input | Non-inverting input with common-mode voltage range (Vcc-) -0.1 to (Vcc+) -1 V. |
| 4 | IN- | input | Inverting input with common-mode voltage range (Vcc-) -0.1 to (Vcc+) -1 V. |
| 5 | VCC+ | power_in | Positive supply voltage for 2.7 to 36 V operation. |
