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 A 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.
