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

HX7533 from HX hengjiaxing, in a SOT-23. 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 Chip ground reference.
3 VIN power_in Unregulated supply input. Absolute max 20V; recommended operating up to 18V. Bypass with 10µF to GND close to the pin.
2 VOUT power_out Regulated 3.3V ±3% output, up to 100mA typical (60mA min). Requires 10µF output capacitor to GND for stability. Dropout ~100mV at IOUT=1mA.
