TPS77618PWPR from Texas Instruments, in a HTSSOP-20-EP. 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 pin; one of nine GND pins on the TSSOP-20 (PWP) package. |
| 2 | GND | power_in | Ground pin; one of nine GND pins on the TSSOP-20 (PWP) package. |
| 3 | GND | power_in | Ground pin; one of nine GND pins on the TSSOP-20 (PWP) package. |
| 4 | NC | unconnected | No internal connection. |
| 5 | EN | input | Negative-polarity enable input; a TTL high signal shuts the regulator down (quiescent current reduced to 1µA at TJ = +25°C), and EN should be tied to ground if shutdown is not used. |
| 6 | IN | power_in | Input voltage; absolute maximum VIN range is -0.3 V to +13.5 V. |
| 7 | IN | power_in | Input voltage; absolute maximum VIN range is -0.3 V to +13.5 V. |
| 8 | NC | unconnected | No internal connection. |
| 9 | GND | power_in | Ground pin; one of nine GND pins on the TSSOP-20 (PWP) package. |
| 10 | GND | power_in | Ground pin; one of nine GND pins on the TSSOP-20 (PWP) package. |
| 11 | GND | power_in | Ground pin; one of nine GND pins on the TSSOP-20 (PWP) package. |
| 12 | GND | power_in | Ground pin; one of nine GND pins on the TSSOP-20 (PWP) package. |
| 13 | OUT | power_out | Regulated output voltage; requires an output capacitor of at least 10µF with ESR between 50mΩ and 1.5Ω to GND for stability. |
| 14 | OUT | power_out | Regulated output voltage; requires an output capacitor of at least 10µF with ESR between 50mΩ and 1.5Ω to GND for stability. |
| 15 | FB/NC | unconnected | No connection on fixed-voltage versions such as the TPS77618; serves as the feedback input (FB) only on the adjustable version. |
| 16 | RESET/PG | output | Open-drain power-good (PG) output on TPS776xx devices, pulled low when the output falls to 92%-98% of nominal; requires a pullup resistor and has a maximum voltage of 16.5 V. |
| 17 | NC | unconnected | No internal connection. |
| 18 | NC | unconnected | No internal connection. |
| 19 | GND | power_in | Ground pin; one of nine GND pins on the TSSOP-20 (PWP) package. |
| 20 | GND | power_in | Ground pin; one of nine GND pins on the TSSOP-20 (PWP) package. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
