1 A, Low IGND, 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 6Lead
DFN3x3 package.
Features
Output Voltage Options: Adjustable, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V

Pin Name
Description
1, 6 IN Voltage inputs which supplies the current to the regulator. Both of these pins should be connected
together for full output current capability
2
GND
Power supply ground of the regulator. Connected to the die through the lead frame. Soldered to the
copper plane allows for effective heat removal.
3 EN For NCP691 and NCP692 this pin functions as Enable Active Low and Enable Active High respect-
ively. For NCP690 this pin has no special meaning and should be left disconnected.
4
OUT
Regulated output voltage
5
SNS
Sense input. This pin should be connected directly to OUT pin.
