TPS77516PWPR 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 reference; the datasheet lists nine GND pins (1, 2, 3, 9, 10, 11, 12, 19, 20) that are all to be tied to ground. |
| 2 | GND | power_in | Ground reference; one of nine GND pins that are all to be tied to ground. |
| 3 | GND | power_in | Ground reference; one of nine GND pins that are all to be tied to ground. |
| 4 | NC | unconnected | No internal connection. |
| 5 | EN | input | Negative polarity enable input; applying a TTL high signal shuts down the regulator, and EN should be tied to ground if shutdown is not used. |
| 6 | IN | power_in | Input voltage; the absolute maximum input voltage range is -0.3 to +13.5 V. |
| 7 | IN | power_in | Input voltage; the absolute maximum input voltage range is -0.3 to +13.5 V. |
| 8 | NC | unconnected | No internal connection. |
| 9 | GND | power_in | Ground reference; one of nine GND pins that are all to be tied to ground. |
| 10 | GND | power_in | Ground reference; one of nine GND pins that are all to be tied to ground. |
| 11 | GND | power_in | Ground reference; one of nine GND pins that are all to be tied to ground. |
| 12 | GND | power_in | Ground reference; one of nine GND pins that are all to be tied to ground. |
| 13 | OUT | power_out | Regulated output voltage; the output voltage at OUT is rated to a maximum of 7 V and output current is internally limited to approximately 1.7 A. |
| 14 | OUT | power_out | Regulated output voltage; the output voltage at OUT is rated to a maximum of 7 V and output current is internally limited to approximately 1.7 A. |
| 15 | FB/NC | unconnected | Feedback input for adjustable versions only; not internally connected on fixed-output versions such as the TPS77516. |
| 16 | RESET | output | Open-drain RESET output on TPS775xx devices, which pulls low when the output drops to between 92% and 98% of its nominal value and requires an external pullup if used. |
| 17 | NC | unconnected | No internal connection. |
| 18 | NC | unconnected | No internal connection. |
| 19 | GND | power_in | Ground reference; one of nine GND pins that are all to be tied to ground. |
| 20 | GND | power_in | Ground reference; one of nine GND pins that are all to be tied to ground. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
