TPS73633DCQR from Texas Instruments, in a SOT-223-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input power supply; supports 1.7V to 5.5V input voltage range for regulator operation. |
| 2 | OUT | output | Regulated output voltage; delivers up to 400mA output current with stable operation without external capacitors. |
| 3 | GND | power_in | Ground reference for regulator. |
| 4 | NR | passive | Noise reduction pin (fixed voltage version only); connect external capacitor to ground to reduce output noise below 30µVRMS. |
| 5 | EN | input | Enable control pin; drive above 1.7V to enable regulator operation, below 0.5V for shutdown mode. |
| 6 | GND | power_in | Ground reference for regulator. |
