NCV4276B Datasheet, PDF (1/12 Pages) ON Semiconductor – 400 mA Low-Drop Voltage Regulator

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.
