XTP2021-330AD1CT

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

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).
