NCV4276 Datasheet, PDF (1/25 Pages) ON Semiconductor – Low-Drop Voltage Regulator

NCV4276, NCV4276A
400 mA Low-Drop Voltage
Regulator
The NCV4276 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 fixed output voltage options of 1.8 V and 2.5 V
with 4% output voltage accuracy while the 3.3 V, 5.0 V, and
adjustable voltage versions are available either in 2% or 4% 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 NCV4276 family is available in
DPAK and D²PAK surface mount packages. The output is stable over
a wide output capacitance and ESR range.
