NCV4290
5.0 V, 450 mA Low-Dropout
Voltage Regulator with
Power Good
The NCV4290 is an integrated low dropout regulator designed
for use in harsh automotive environments. It includes wide
operating temperature and input voltage ranges. The output is
regulated at 5.0 V and is rated to 450 mA of output current. It also
provides a number of features, including overcurrent protection,
overtemperature protection and a programmable microprocessor
power good signal. The NCV4290 is available in the DPAK and
D²PAK surface mount packages. The output is stable over a wide
output capacitance and ESR range.
