XTP2021-180AD1CT 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; for the XTP2021-1.8 variant (ordering number XTP2021-180AD1CT) the fixed output voltage is 1.8V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Enable control input; driving it low turns the regulator off and reduces current to 100nA (typical), with input voltage range 1.8V to 5.5V. |
| 4 | VIN | power_in | Input of supply voltage, specified for 1.8V to 5.5V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
