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.
