LP3993-33B3F

LOWPOWER · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

LP3993-33B3F from LOWPOWER, in a SOT-23. 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 GND power_in Ground reference pin for the regulator.
2 Vout power_out Regulated output pin, rated for 200mA output loading current; the -33 variant regulates to 3.3V.
3 Vin power_in Power input pin; recommended supply range is Vout+1V to 24V, with an absolute maximum of 30V.
