TPS73801DCQR 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 | Power supply input; withstands reverse voltages up to ±20 V; 1-10 µF bypass capacitor recommended if more than six inches from main input filter. |
| 2 | OUT | power_out | Regulated power output (1.21 V to 20 V); minimum 10 µF ceramic output capacitor required to prevent oscillations. |
| 3 | GND | power_in | Ground reference. |
| 4 | FB | input | Feedback input to error amplifier; internally clamped to ±7 V with 3 μA bias current flowing into pin; maintains 1.21 V reference voltage for 1.21-20 V output range. |
| 5 | EN | input | Enable control input; pulling low puts device in low-power shutdown state; can be driven by 5-V logic or open-collector gate with typical current 3 μA; must be tied to IN pin if unused. |
| 6 | GND | power_in | Ground reference. |
