NCV4275C/D
NCV4275C
450 mA Low-Drop Voltage
Regulator with Reset
The NCV4275C 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 NCV4275C is available in the DPAK and
D
2
PAK surface mount packages. The output is stable over a wide
output capacitance and ESR range. The NCV4275C is pin for pin
compatible with NCV4275A.
