TPS76633DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC/FB | unconnected | Not internally connected for fixed 3.3V version; leave open or tie to ground for improved thermal performance. |
| 2 | PG | tri_state | Power-good open-drain output; pulled low when output voltage falls below threshold; requires external pullup resistor. |
| 3 | GND | power_in | Ground pin. |
| 4 | EN | input | Enable input; driving low enables device output, driving high (above 1.2V typical) disables device output. |
| 5 | IN | power_in | Input voltage supply pin; rated 2.5V to 16V DC; place 1µF minimum input capacitor close to IN and GND pins. |
| 6 | IN | power_in | Input voltage supply pin; rated 2.5V to 16V DC; place input capacitor close to IN and GND pins for noise reduction. |
| 7 | OUT | power_out | Regulated 3.3V output voltage pin supplying up to 250mA; place 2.2µF to 220µF output capacitor (ESR up to 2Ω) close to OUT and GND pins. |
| 8 | OUT | power_out | Regulated output voltage pin; place output capacitor (2.2µF to 220µF, ESR up to 2Ω) close to OUT and GND pins. |
