NCP4588
200 mA, Output Capacitor
Free, LDO Linear Voltage
Regulator
The NCP4588 is a CMOS 200mA LDO which is stable without an
output capacitor. This results in a reduction in component count, cost
and board area, as well as contributing to a more robust solution in
hostile environments. With quiescent current < 9.5
mA
and
PSRR > 60 dB, the device is an excellent trade off between the two
features. The family is available in a variety of packages: SC−70,
SOT23 and a small, ultra thin 1.2 x 1.2 x 0.4 mm XDFN.
