LP3980-33QVF

LOWPOWER · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · XDFN-4-EP(1x1)

LP3980-33QVF from LOWPOWER, in a XDFN-4-EP(1x1). 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 OUT power_out Regulated output voltage (3.3 V for the -33 option) that delivers up to 300 mA; the datasheet calls for at least 1 µF ceramic output capacitance with ESR above 25 mΩ and placement within 0.5 inch of the pin.
2 GND power_in Ground reference for the regulator, to be returned to a clean analog ground.
3 EN input Enable input: the LDO turns on when the voltage exceeds 1.4 V and shuts down when it falls below 0.4 V, and it can be tied to VIN for continuous operation.
4 VIN power_in Input supply voltage, rated 1.6 V to 5.5 V, with a 1 µF input capacitor placed within 0.5 inch of the pin.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
