TPS79633KTTR 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 | EN | input | Enable input: drive high to turn the regulator on and low to put it in shutdown; may be tied to IN if unused (max VEN 5.5V on old die, absolute max VIN + 0.3V). |
| 2 | IN | power_in | Regulator input supply, 2.7V to 5.5V on the old die, bypassed with a 2.2µF or larger ceramic capacitor to GND close to the device. |
| 3 | GND | power_in | Regulator ground. |
| 4 | OUT | power_out | Regulator output, requires a 1µF or larger ceramic output capacitor to GND for stability, rated for up to 1A. |
| 5 | NR | passive | Noise-reduction pin on the fixed-voltage old die: an external capacitor (0.1µF or less) bypasses bandgap noise to improve PSRR and lower output noise. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
