# XTP2038-180AS2CT

**XTX** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

XTP2038-180AS2CT from XTX, in a SOT-23-5L. 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; the datasheet specifies an input voltage range of 1.8V to 5.5V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Enable control input; the regulator is turned off when this pin is driven low, reducing current to about 10nA typical. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator, rated for up to 500mA output current. |
