Overview
The NCV4264-2ST33T3G is a low dropout linear voltage regulator produced by ON Semiconductor. It is functionally and pin-for-pin compatible with the NCV4264 but features a lower quiescent current consumption. This regulator is designed to supply 100 mA of output current with ±2.0% output voltage accuracy. It is available in a 3.3 V fixed output version and is internally protected against various faults, including 45 V input transients, input supply reversal, output overcurrent, and excess die temperature. No external components are required to enable these protection features.
