NCP4569

300 mA CMOS LDO with

Shutdown and V_REFBypass

The NCP4569 is a fixed output, high accuracy (typically "0.5%)

CMOS upgrade for older (bipolar) low dropout regulators. Total

supply current is typically 50 µA at full load (20 to 60 times lower than

in bipolar regulators).

NCP4569 key features include ultra low noise operation (plus

optional Bypass input); very low dropout voltage (typically 240 mV at

full load), and fast response to step changes in load. Supply current is

reduced to 0.05 µA (typical) and V

shutdown input is low.

The NCP4569 incorporates both over–temperature and over–current

protection. The NCP4569 is stable with an output capacitor of only

1.0 µF and has a maximum output current of 300 mA.
