NCP134
500 mA, Very Low Dropout
Bias Rail CMOS Voltage
Regulator
The NCP134 is a 500 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
NCP134 features low IQ consumption. The XDFN4 1.2 mm x 1.2 mm
package is optimized for use in space constrained applications.
