MD8236A

Shanghai Mingda Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

MD8236A 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 GND power_in Ground pin; keep VIN, VOUT and GND wiring low-impedance.
2 VIN power_in Input supply pin; maximum operating input 40V (absolute maximum 45V), with at least 1.0µF input capacitor recommended.
3 VOUT power_out Regulated 3.6V output, 150mA rated with about 300mA typical current limit; must not exceed VIN+0.3V, with at least 2.2µF output capacitor recommended.
