NCP4555, NCP4586

100 mA and 150 mA CMOS

LDOs with Shutdown and

Error Output

The NCP4555 and NCP4586 are high accuracy (typically "0.5%)

CMOS upgrades for older (bipolar) low dropout regulators. Designed

specifically for battery–operated systems, the devices’ CMOS

construction eliminates wasted ground current, significantly

extending battery life. Total supply current is typically 50 µA at full

load (20 to 60 times lower than in bipolar regulators).

The devices’ key features include ultra low noise operation, very

low dropout voltage – typically 180 mV (NCP4555) and 270 mV

(NCP4586) at full load – and fast response to step changes in load. An

error output (ERROR) is asserted when the devices are

out–of–regulation (due to a low input voltage or excessive output

current). ERROR can be used as a low battery warning or as a

processor RESET signal (with the addition of an external RC

and ERROR are disabled when the shutdown input is low. The devices

incorporate both over–temperature and over–current protection.

The NCP4555 and NCP4586 are stable with an output capacitor of

only 1.0 µF and have a maximum output current of 100 mA and

150 mA, respectively. For higher output current regulators, please see
