TPS73401DRVR from Texas Instruments, in a WSON-6-EP(2x2). 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 | OUT | power_out | Regulator output; needs a small capacitor (total typical capacitance ≥ 2.0µF ceramic) to ground to assure stability. |
| 2 | FB | input | Adjustable version only; input to the control loop error amplifier, used to set the output voltage of the device (internal reference 1.208V typ). |
| 3 | GND | power_in | Ground pin. |
| 4 | EN | input | Driving EN high turns on the regulator and driving it low puts the regulator into shutdown mode; can be connected to IN if not used (high 1.2V to VIN, low 0 to 0.4V). |
| 5 | N/C | unconnected | Not internally connected; must either be left open or tied to GND. |
| 6 | IN | power_in | Input supply; input voltage range 2.7V to 6.5V. |
| 7 | GND | power_in | Exposed thermal pad (Pad); must be tied to GND. |
