MD7671B50SF4

MD7671 series are highly accurate, low noise, high power supply rejection ratio (PSRR), low-dropout voltage regulator (LDO) with high output current capability manufactured in CMOS processes. It can deliver up to 1A of current while consuming 40μA of quiescent current. Internal circuitry includes a reference voltage generator, an error amplifier, driver transistor, over-current protection circuit, short-circuit protection circuit, thermal shutdown circuit and a phase compensation circuit. The MD7671 operates by default as a fixed output voltage regulator (default output voltage: 5V) while usage of an external resistor divider allows adjustable out voltages as low as 0.7V. Additional features include enable function, power good flag and output noise reduction pin.
