NCP720

NCP720 350mA, Very Low Dropout Bias Rail CMOS Voltage Regulator The NCP720 is a 350 mA VLDO equipped with NMOS pass transistor and a separate bias supply voltage (VBIAS). The device provides very stable, accurate output voltage with low noise suitable for space constrained, noise sensitive applications. In order to optimize performance for battery operated portable applications, the NCP720 features low IQ consumption. The WDFN6 2 mm x 2 mm package is optimized for use in space constrained applications. Features Input Voltage Range: 0.8 V to 5.5 V Bias Voltage Range: 2.4 V to 5.5 V Fixed Output Voltage Device Output Voltage Range: 0.8 V to 2.1 V ±2% Accuracy over Temperature Ultra−Low Dropout: 110 mV typically at 350 mA Very Low Bias Input Current of Typ. 80 mA Very Low Bias Input Current in Disable Mode: Typ. 0.5 mA Low Noise, High PSRR Built−In Soft−Start with Monotonic VOUT Rise Stable with a 2.2 mF Ceramic Capacitor Available in WDFN6 − 2 mm x 2 mm Package These are Pb−Free Devices Typical Applications Battery−powered Equipment Smartphones, Tablets Cameras, DVRs, STB and Camcorders VBIAS VIN NCP720 BIAS OUT IN EN GND VOUT 1.5 V @ 350 mA 2.2 mF VEN Figure 1.
