NCV4290: 450 mA LDO Linear Voltage Regulator with Power Good
The NCV4290 is an integrated low dropout regulator designed for use in harsh automotive enviroments. It includes wide operating temperature and input voltage ranges. The output is regulated at 5 V and is rated to 450 mA of output current. It also provides a number of features, including overcurrent protection, overtemperature protection and a programable microprocessor power good signal. The NCV4290 is available in the DPAK and D2PAK surface mount package. The output is stable over wide output capcitance and ESR range.
