MD7150H

Shanghai Mingda Microelectronics · Linear Voltage Regulators (LDO) · SOT-23-3L

MD7150H from Shanghai Mingda Microelectronics, in a SOT-23-3L. 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 reference for the output voltage.
2 VDD power_in Power input terminal; the input voltage may be up to 32V (absolute maximum VIN 32V), and the output is regulated only when VIN is above VOUT plus the dropout.
3 VOUT power_out Regulated 5.0V output terminal; the datasheet states VOUT must not exceed VIN+0.3V, and a 2.2µF or larger output capacitor is required between VOUT and GND.
