NCP4640 fiche technique
NCP4640
50 mA, Wide Input Range,
Voltage Regulator
The NCP4640 is a CMOS 50 mA linear voltage regulator with high
input voltage and ultralow supply current. It incorporates multiple
protection features such as peak current limit, short circuit current
limit and thermal shutdown to ensure a very robust device.
A high maximum input voltage tolerance of 50 V and a wide
temperature range make the NCP4640 suitable for a variety of
demanding applications.
