HT7344-A

GUOXIN JIAPIN SEMICONDUCTOR · Linear Voltage Regulators (LDO) · SOT-89-3

HT7344-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 of the HT73XX-A LDO regulator.
2 VIN power_in Input terminal; the datasheet gives an absolute maximum input voltage of 15 V and states regulation is maintained up to 12 V.
3 VOUT output Regulated output terminal, with output voltage accuracy of ±3% and a 60 mA output-current test condition in the electrical characteristics.
