NCV4299C
150 mA Low-Dropout
Voltage Regulator
The NCV4299C 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.
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 80
mA
with a 100
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. 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.
