XTP2021-150AD1CT from XTX, in a DFN1x1-4L. 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 | VOUT | power_out | Output of the regulator, fixed at the voltage selected by the ordering code (0.9V to 3.3V for the XTP2021 family); the -150 suffix corresponds to 1.5V. |
| 2 | GND | power_in | Ground reference for the regulator. |
| 3 | EN | input | Enable control input; the datasheet gives VIH of 0.9V (rising) and VIL of 0.60V (falling), with VOUT,EN to GND limited to -0.3V to 6V. |
| 4 | VIN | power_in | Input of supply voltage; recommended range 1.8V to 5.5V, with VIN to GND absolute maximum of 6.5V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
