MD6127C24

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

MD6127C24 from Shanghai Mingda Microelectronics, in a SOT-23-5. 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 DS input Delay-time ON/OFF select input that must be fixed at a low or high level; a high level shortens the release delay to about 110-330 µs (versus about 130-290 ms at low), with VSH ≥ 1.0 V and VSL ≤ 0.3 V at VDD = 6.0 V.
2 VSS power_in Ground terminal, the reference for the supply and output levels (VDD − VSS absolute maximum rating is 15 V).
3 NC unconnected No connection; the pin is not connected internally and is not used in the circuit.
4 VOUT output Voltage detection output: NMOS open-drain output rated VSS−0.3 V to VSS+15 V, CMOS output rated VSS−0.3 V to VDD+0.3 V, with output current absolute maximum 50 mA.
5 VDD power_in Detection voltage input and supply, with operating voltage range 1 V to 12 V and absolute maximum VDD − VSS of 15 V.
