MD5130

Shanghai Mingda Microelectronics · Linear Voltage Regulators (LDO) · SOT-23-5L

MD5130 from Shanghai Mingda Microelectronics, in a SOT-23-5L. 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 VIN power_in Input supply pin, operating range 1.5V to 7V (absolute maximum 8.0V), with a 1.0uF or larger input capacitor recommended.
2 GND power_in Ground pin; the internal COUT auto-discharge switch connects between VOUT and GND.
3 CE input Chip enable input, active high: VCEH is 1.0V to 6.0V to enable and VCEL is 0V to 0.38V to shut down and discharge COUT.
4 NC unconnected No connection pin.
5 VOUT power_out Regulated 3.0V output (MD5130, ±2%) delivering up to 300mA, with a 0.1uF or larger output capacitor; must not exceed VIN+0.3V.
