NCV4275
5.0 V, 450 mA Low-Drop
Voltage Regulator
The NCV4275 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
reset. The NCV4275 is available in the DPAK and D2PAK surface
mount packages. The output is stable over a wide output capacitance
and ESR range.
