HT7325-A from GUOXIN JIAPIN SEMICONDUCTOR, 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 | Chip ground terminal (芯片接地端) for the HT73XX-A series LDO. |
| 2 | VIN | power_in | Input pin that starts the regulator; the datasheet states output regulation is maintained with input up to 12 V, with an absolute maximum input voltage of 15 V. |
| 3 | VOUT | power_out | Regulated output pin; for HT7325-A the output is 2.5 V typical with ±3% accuracy (2.425 V to 2.575 V) at VIN = 3.5 V and IOUT = 40 mA. |
