NCV4275A

5.0 V, 3.3 V 450 mA

Low-Dropout Voltage

Regulator with Reset

The NCV4275A 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 or 3.3 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 reset. The NCV4275A is available in the DPAK and

D PAK surface mount packages. The output is stable over a wide

output capacitance and ESR range. The NCV4275A is pin for pin

compatible with NCV4275.
