TPS7B8633QDDARQ1 from Texas Instruments, in a SO-8. 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 | Regulated 3.3 V output voltage pin; capacitor (2.2 µF to 220 µF) required between OUT and GND to ensure stability. |
| 2 | FB/NC | unconnected | No connection pin (NC) for fixed output 3.3 V version; may be left floating or connected to GND. |
| 3 | NC | unconnected | No internal connection; pin may be left floating or connected to GND for optimal thermal performance. |
| 4 | NC | unconnected | No internal connection; pin may be left floating or connected to GND for optimal thermal performance. |
| 5 | GND | power_in | Ground pin; must be connected to thermal pad with low impedance connection. |
| 6 | NC | unconnected | No internal connection; pin may be left floating or connected to GND for optimal thermal performance. |
| 7 | EN | input | Enable pin; device disabled when enable voltage is below VIL (0.7 V); do not leave floating as pin has high impedance. |
| 8 | IN | power_in | Input power supply voltage pin (3 V to 40 V); capacitor (0.1 µF to 1 µF) required between IN and GND for optimal transient response. |
