XTP2021-330AD1CT 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 3.3V for this variant, with absolute maximum VOUT to GND of -0.3 V to 6 V and VOUT to VIN of -6 V to 0.3 V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Enable control input with a rising threshold VIH of 0.9 V and a falling threshold VIL of 0.60 V, and an absolute maximum of -0.3 V to 6 V to GND. |
| 4 | VIN | power_in | Input supply voltage with a recommended range of 1.8 V to 5.5 V and an absolute maximum of -0.3 V to 6.5 V to GND. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
