TPS77516DR 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 | Ground connection for the regulator. |
| 2 | EN | input | Negative polarity enable input; a TTL high signal shuts down the regulator, and EN should be tied to ground if the shutdown feature is not used. |
| 3 | IN | power_in | Input voltage pin; pins 3 and 4 are both IN. |
| 4 | IN | power_in | Input voltage pin; pins 3 and 4 are both IN. |
| 5 | OUT | power_out | Regulated output voltage; requires an output capacitor of at least 10µF between OUT and GND with ESR between 50mΩ and 1.5Ω. |
| 6 | OUT | power_out | Regulated output voltage; pins 5 and 6 are both OUT and require the same output capacitor between OUT and GND with ESR between 50mΩ and 1.5Ω. |
| 7 | FB/NC | input | Feedback input for setting the output voltage on the adjustable version only; the pin table states it is not internally connected on adjustable versions, so it is a no-connect on the fixed-voltage TPS77516. |
| 8 | RESET/PG | output | Open-drain RESET output on TPS775xx devices (the TPS77516 belongs to this family); it requires a pullup resistor, can be left floating if unused, and asserts low when the output drops to between 92% and 98% of nominal. |
