TPS72501KTTR from Texas Instruments, in a TO-263-5. 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 | ENABLE | input | Enable input; the absolute maximum voltage range on EN is -0.3 V to VI + 0.3 V. |
| 2 | IN | power_in | Input supply voltage; recommended VI is 1.8 V to 6 V and the absolute maximum range is -0.3 V to 7 V. |
| 3 | GND | power_in | Ground terminal; the tab is also GND on the KTT package. |
| 4 | OUT | power_out | Regulated output voltage; continuous output current is 0 to 1 A and the absolute maximum voltage on OUT is 6 V. |
| 5 | RESET/FB | bidirectional | On the TPS72501 this is the feedback input of the adjustable regulator (reference 1.220 V); on the fixed options it is an open-drain active-low RESET output that asserts when the output falls more than 5% below nominal and needs a pullup resistor. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
