HT7330-A

UMW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

HT7330-A from UMW, in a SOT-89-3. 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 for the regulator; all datasheet voltages are referenced to GND.
2 VIN power_in Supply voltage input, operating up to 12V (absolute maximum 15V), with a 10µF capacitor C1 shown in the typical application.
3 VOUT power_out Regulated 3.0V output (±3%) for the HT7330-A, with a 10µF capacitor C2 shown in the typical application.
