NCP690 Datasheet, PDF (1/14 Pages) ON Semiconductor – 1 A, Low IGND, Very Low Dropout Regulator (VLDO) with/without Enable

NCP690, NCP691, NCP692
1 A, Low I_GND, Very Low
Dropout Regulator (VLDO)
with/without Enable
The NCP690, NCP691, NCP692 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
