XTP2021-290AS2CT from XTX, in a SOT-23-5. 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 | VIN | power_in | Input of supply voltage, operating range 1.8V to 5.5V. |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable control input; a low level turns the output off and reduces current to about 100nA (typical). |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator, up to 300mA output current (2.9V fixed output for this MPN). |
