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. |
