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
