TPS76733QPWP 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/HSINK | power_in | Ground/heatsink pin that is tied to the regulator ground and the PowerPAD heatsink; it should be connected to the board ground plane for heat removal. |
| 2 | GND/HSINK | power_in | Ground/heatsink pin that is tied to the regulator ground and the PowerPAD heatsink; it should be connected to the board ground plane for heat removal. |
| 3 | GND | power_in | Regulator ground pin. |
| 4 | NC | unconnected | No connect; no internal connection to the device. |
| 5 | EN | input | Enable input; a TTL high signal shuts down the regulator and reduces quiescent current to 1 µA at TJ = 25°C, and if the shutdown feature is not used EN should be tied to ground. Voltage at EN is limited to −0.3 V to VI + 0.3 V. |
| 6 | IN | power_in | Regulator input voltage; recommended input range is 2.7 V to 10 V, with an absolute maximum of 13.5 V. |
| 7 | IN | power_in | Regulator input voltage; recommended input range is 2.7 V to 10 V, with an absolute maximum of 13.5 V. |
| 8 | NC | unconnected | No connect; no internal connection to the device. |
| 9 | GND/HSINK | power_in | Ground/heatsink pin that is tied to the regulator ground and the PowerPAD heatsink; it should be connected to the board ground plane for heat removal. |
| 10 | GND/HSINK | power_in | Ground/heatsink pin that is tied to the regulator ground and the PowerPAD heatsink; it should be connected to the board ground plane for heat removal. |
| 11 | GND/HSINK | power_in | Ground/heatsink pin that is tied to the regulator ground and the PowerPAD heatsink; it should be connected to the board ground plane for heat removal. |
| 12 | GND/HSINK | power_in | Ground/heatsink pin that is tied to the regulator ground and the PowerPAD heatsink; it should be connected to the board ground plane for heat removal. |
| 13 | OUT | power_out | Regulated output voltage; output current is limited to 0 to 1.0 A and the output voltage absolute maximum is 7 V. |
| 14 | OUT | power_out | Regulated output voltage; output current is limited to 0 to 1.0 A and the output voltage absolute maximum is 7 V. |
| 15 | FB/NC | input | Feedback input for the adjustable version (1.5 V to 5.5 V); on fixed-output versions such as the TPS76733 this pin is no connect, and on the adjustable version routing should minimize noise pickup. |
| 16 | RESET | output | Open-drain RESET output that goes low when the output falls to between 92% and 98% of nominal and requires an external pullup; absolute maximum is 16.5 V. |
| 17 | NC | unconnected | No connect; no internal connection to the device. |
| 18 | NC | unconnected | No connect; no internal connection to the device. |
| 19 | GND/HSINK | power_in | Ground/heatsink pin that is tied to the regulator ground and the PowerPAD heatsink; it should be connected to the board ground plane for heat removal. |
| 20 | GND/HSINK | power_in | Ground/heatsink pin that is tied to the regulator ground and the PowerPAD heatsink; it should be connected to the board ground plane for heat removal. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
