TPS77733D from Texas Instruments, in a SOIC-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 | GND | power_in | Regulator ground connection point. |
| 2 | EN | input | Enable input; TTL high signal shuts down the regulator. |
| 3 | IN | input | Input supply voltage. |
| 4 | IN | input | Input supply voltage. |
| 5 | OUT | output | Regulated output voltage. |
| 6 | OUT | output | Regulated output voltage. |
| 7 | FB/NC | unconnected | No internal connection for fixed-output version; feedback input voltage for adjustable device. |
| 8 | RESET | output | Open-drain power-on reset output with 200-ms delay triggered on output undervoltage condition. |
