NCV4264-2
Low I
Q
Low Dropout
Linear Regulator
The NCV4264−2 is functionally and pin for pin compatible with
NCV4264 with a lower quiescent current consumption. Its output
stage supplies 100 mA with
"2.0%
output voltage accuracy.
Maximum dropout voltage is 500 mV at 100 mA load current.
It is internally protected against 45 V input transients, input supply
reversal, output overcurrent faults, and excess die temperature. No
external components are required to enable these features.
