XTP2021-150AD1CT

XTX · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN1x1-4L

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).
