MD8336

Shanghai Mingda Microelectronics · Linear Voltage Regulators (LDO) · SOT-89-3

MD8336 from Shanghai Mingda Microelectronics, 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 VOUT power_out Regulated output (3.6V option, up to 300mA, ±2% accuracy) driven by a P-channel pass MOSFET; needs COUT of 1.0uF or more and must not exceed VIN+0.3V.
2 VIN power_in Input supply, 2.2V to 40V operating (absolute maximum 45V), with CIN of 1.0uF or more placed close to the IC.
3 GND power_in Ground pin of the regulator, which draws about 1.5uA typical quiescent current at no load for 3.0V to 5.3V outputs.
