MD7130H

Shanghai Mingda Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

MD7130H 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 (接地端); the datasheet gives no further electrical limit for this pin.
2 VDD power_in Power input terminal; the absolute maximum input voltage VIN is 32 V.
3 VOUT power_out Regulated output; VOUT must not exceed VIN+0.3 V to avoid reverse current damaging the IC, and short-circuit current is limited to about 30 mA.
