HX hengjiaxing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

HX7333 from HX hengjiaxing, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground / common return for input and output. Connect to system ground plane; the bottom of both input and output decoupling capacitors returns here.
2 VOUT power_out Regulated 3.3 V output (±3%, 3.201-3.399 V). Requires a 10 µF ceramic output capacitor to GND for stability. Rated for up to 250 mA continuous with VIN ≥ 4.3 V; typical dropout 90 mV at 40 mA.
3 VIN power_in Unregulated input supply. Recommended operating range 4.3 V to 12 V (absolute max 15 V). Bypass with a 10 µF ceramic capacitor to GND close to the pin.
