NCV4299
150 mA Low−Dropout
Voltage Regulator
The NCV4299 is a family of precision micropower voltage regulators
with an output current capability of 150 mA. It is available in 5.0 V or
3.3 V output voltage, and is housed in an 8−lead SON and in a 14−lead
SON (fused) package.
The output voltage is accurate within "2% with a maximum
dropout voltage of 0.5 V at 100 mA. Low Quiescent current is a
feature drawing only 90 mA with a 1 mA load. This part is ideal for any
and all battery operated microprocessor equipment.
The device features microprocessor interfaces including an
adjustable reset output and adjustable system monitor to provide
shutdown early warning. An inhibit function is available on the
14−lead part. With inhibit active, the regulator turns off and the device
consumes less than 1.0 mA of quiescent current.
The part can withstand load dump transients making it suitable for
use in automotive environments.
