NCV4275A: Linear Voltage Regulator, LDO, 450 mA, with Reset

Product Description
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 is pin for pin compatible with NCV4275 and can be used as replacement of this device when EMC sensitivity is critical.
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 D2PAK surface mount packages. The output is stable over a wide output capacitance and ESR range.
