TPS77533PWP from Texas Instruments, in a HTSSOP-20. 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, listed as GND/HSINK in the pin configuration and intended to be tied to the ground plane for heat sinking. |
| 2 | GND | power_in | Ground pin, listed as GND/HSINK in the pin configuration and intended to be tied to the ground plane for heat sinking. |
| 3 | GND | power_in | Ground pin, listed as GND/HSINK in the pin configuration and intended to be tied to the ground plane for heat sinking. |
| 4 | NC | unconnected | No internal connection. |
| 5 | EN | input | Negative-polarity enable input; a TTL high shuts the regulator down, and the absolute maximum voltage at EN is -0.3 V to +16.5 V. |
| 6 | IN | power_in | Input voltage pin for the regulator; the absolute maximum input voltage range is -0.3 V to +13.5 V. |
| 7 | IN | power_in | Input voltage pin for the regulator; the absolute maximum input voltage range is -0.3 V to +13.5 V. |
| 8 | NC | unconnected | No internal connection. |
| 9 | GND | power_in | Ground pin, listed as GND/HSINK in the pin configuration and intended to be tied to the ground plane for heat sinking. |
| 10 | GND | power_in | Ground pin, listed as GND/HSINK in the pin configuration and intended to be tied to the ground plane for heat sinking. |
| 11 | GND | power_in | Ground pin, listed as GND/HSINK in the pin configuration and intended to be tied to the ground plane for heat sinking. |
| 12 | GND | power_in | Ground pin, listed as GND/HSINK in the pin configuration and intended to be tied to the ground plane for heat sinking. |
| 13 | OUT | power_out | Regulated output voltage pin; the absolute maximum voltage range at OUT is 7 V. |
| 14 | OUT | power_out | Regulated output voltage pin; the absolute maximum voltage range at OUT is 7 V. |
| 15 | FB/NC | unconnected | Feedback pin used only on the adjustable versions; on the fixed-output TPS77533 it is not internally connected. |
| 16 | RESET/PG | output | Open-drain RESET output on the TPS775xx (this fixed 3.3 V part), taking the output low when the regulated output falls to 92%-98% of nominal; it needs a pullup resistor and its maximum voltage is 16.5 V. |
| 17 | NC | unconnected | No internal connection. |
| 18 | NC | unconnected | No internal connection. |
| 19 | GND | power_in | Ground pin, listed as GND/HSINK in the pin configuration and intended to be tied to the ground plane for heat sinking. |
| 20 | GND | power_in | Ground pin, listed as GND/HSINK in the pin configuration and intended to be tied to the ground plane for heat sinking. |
| 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)
