HT7550M 24V

PUOLOP · Linear Voltage Regulators (LDO) · SOT-89-3

HT7550M 24V from PUOLOP, 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 pin (芯片接地端).
2 VIN power_in Start-up input pin; the absolute maximum input voltage is -0.3 V to +26 V, and the datasheet specifies a DC input voltage of 24 V maximum.
3 VOUT power_out Chip output pin; for the HT7550M the output is 5.0 V typical (4.850 V to 5.150 V), and an output-to-ground capacitor greater than 2.2 μF, with tantalum recommended, must be used.
