HE2280A33PR

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

HE2280A33PR from HEERMICR, 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 pin, shared reference for the input and output capacitors.
2 VIN power_in Supply input accepting up to 80V (absolute maximum VSS+80.0V, recommended maximum 60V), decoupled with a 10µF ceramic capacitor to GND.
3 VOUT power_out Regulated 3.3V output delivering up to 150mA, with a 10µF ceramic output capacitor recommended and absolute maximum of VSS+6.0V.
