MD7530H

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

MD7530H 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 (接地端) and reference for the regulator; the datasheet gives no further electrical limit for this pin.
2 VDD power_in Power input; the absolute maximum input voltage (VIN) is 32 V, the input voltage rating is 30 V, and output regulation is maintained up to 30 V.
3 VOUT power_out Regulated output; VOUT must not exceed VIN+0.3 V because the internal parasitic diode can cause reverse-current damage, and the output short-circuit current is limited to about 180 mA.
