NCP590
Dual Output, High Accuracy,
Ultra Low Dropout
CMOS LDO
The NCP590 is a family of very high precision dual-output CMOS
LDOs offered in a 2x2 DFN8 package. Each output is capable of
delivering up to 300 mA and is available in voltages from 0.8 V to
5 V.
The set point output voltage is accurate to within ±0.9% with an
operating voltage input up to 5.5 V. With its ultra low dropout
characteristics and low quiescent and ground current consumption,
the NCP590 is ideal for all battery operated consumer and
microprocessor applications. The NCP590 is protected against short
circuit and thermal overload conditions.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
