NCV8690
1 A, Low IGND, Very Low
Dropout Regulator (VLDO)
with/without Enable
The NCP690, NCP691, NCP692, NCV8690 CMOS LDO family
provides 1 A of output current with enhanced ESD in either fixed
voltage options or an adjustable output voltage from 5.0 V down to
1.25 V. This device is designed for space constrained and portable
battery powered applications and offer additional features such as high
PSRR, low Quiescent and Ground current consumption, low noise
operation, short circuit and thermal protection. The device is designed
to be used with low cost ceramic capacitors and is packaged in the
6−Lead DFN3x3 package.
Features
