TPS77518DR 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 reference pin for the regulator. |
| 2 | EN | input | Negative-polarity enable input; a TTL high signal shuts the regulator down and reduces quiescent current to 1µA at TJ = +25°C, and EN should be tied to ground if the shutdown feature is not used. |
| 3 | IN | power_in | Input voltage pin; absolute maximum VIN range is -0.3 V to +13.5 V, and a ceramic bypass capacitor of 0.047µF or larger improves transient response when the device is far from the supply. |
| 4 | IN | power_in | Input voltage pin (second IN pin, internally tied to pin 3); absolute maximum VIN range is -0.3 V to +13.5 V. |
| 5 | OUT | power_out | Regulated output voltage; requires an output capacitor from OUT to GND with a minimum of 10µF and ESR between 50mΩ and 1.5Ω. |
| 6 | OUT | power_out | Regulated output voltage (second OUT pin, internally tied to pin 5); same output capacitor requirement applies. |
| 7 | FB/NC | unconnected | Feedback input on adjustable versions only; for the fixed-voltage TPS77518 this pin is not internally connected. |
| 8 | RESET/PG | output | Open-drain RESET output on TPS775xx devices (TPS77518 family) that goes low when the output falls to 92%-98% of nominal, requires a pullup resistor, and has a maximum voltage of 16.5 V. |
