NCV4276B

400 mA Low-Drop Voltage

Regulator

The NCV4276B is a 400 mA output current integrated low dropout

regulator family designed for use in harsh automotive environments.

It includes wide operating temperature and input voltage ranges. The

device is offered with adjustable voltage versions available in 2%

output voltage accuracy. It has a high peak input voltage tolerance

and reverse input voltage protection. It also provides overcurrent

protection, overtemperature protection and inhibit for control of the

state of the output voltage. The NCV4276B is available in DPAK

surface mount package. The output is stable over a wide output

capacitance and ESR range. The NCV4276B has improved startup

behavior during input voltage transients.
