HT7544-2-MS

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

HT7544-2-MS from MSKSEMI, 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.
2 VIN power_in Input supply pin; the datasheet states the series withstands a voltage of 30V.
3 VOUT power_out Regulated output pin; the output stabilization capacitor is compatible with low ESR ceramic capacitors.
