NCP4588

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. Features Operating Input Voltage Range: 1.4 V to 5.25 V Output Voltage Range: 1.0 to 4.2 V (available in 0.1 V steps) Output Voltage Accuracy: 1% Quiescent Current: 9.5 mA Standby Current: 0.1 mA Very Low Dropout: 270 mV (IOUT = 200 mA, VIN = 3.0 V) High PSRR: 70 dB at 1 kHz, VOUT ≤ 1.2 V 65 dB at 1 kHz, 1.2 < VOUT < 2.2 V 60 dB at 1 kHz, VOUT ≥ 2.2 V Line Regulation 0.02%/V Typ. Current Fold Back Protection: 50 mA at short Stable with no Output Capacitor Available in SC−70, XDFN and SOT23 Package These are Pb−Free Devices Typical Applications Battery Powered Equipments Portable Communication Equipments Cameras, VCRs and Camcorders VIN C1 100 n NCP4588x VIN VOUT CE GND VOUT C2 100n* * output capacitor may be omitted Figure 1.
