NCV4276BDS50R4G Datasheet, PDF (1/18 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 3.3 V, 5.0 V, and 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
family is available in DPAK and D2PAK surface mount packages.
The output is stable over a wide output capacitance and ESR range.
The NCV4276B has improved startup behavior during input voltage
transients.
