HT7544-1

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

HT7544-1 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 pin of the regulator, shown as GND in the principle block diagram.
2 VIN power_in Regulator input pin; the maximum input voltage is 30V.
3 VOUT power_out Regulated output pin; the 75xx series output range is 3.0V to 5.0V, and the HT7544 is specified at 4.4V typical (4.268V to 4.532V).
