MD7136H

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

MD7136H 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 terminal of the regulator; the datasheet gives no additional limits for this pin.
2 VDD power_in Power supply input, rated up to 32 V (absolute maximum VIN 32 V), with overvoltage protection stated for the input.
3 VOUT power_out Regulated output that must not be driven more than 0.3 V above VIN, and requires an output capacitor of at least 2.2 µF (tantalum) or 10 µF (aluminum electrolytic) to remain stable.
