MD8410

Shanghai Mingda Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

MD8410 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 Power input pin; the datasheet specifies an input voltage range of 2.2 V to 40 V (absolute maximum -0.3 V to 45 V).
2 GND power_in Ground pin, the reference for the regulator.
3 VOUT power_out Regulated output voltage pin; the VOUT potential must not exceed VIN+0.3 V.
4 NC unconnected No internal connection.
5 EN input Enable pin: drive high (VENH 1.5 V to 40 V) to enable the device and low (VENL 0 V to 0.6 V) to put it into low current shutdown.
