www.DataSheet4U.com CS8481 3.3 V/250 mA, 5.0 V/100 mA Micropower Low Dropout Regulator with ENABLE The CS8481 is a precision, dual Micropower linear voltage regulator.

The switched 3.3 V primary output (VOUT1) supplies up to 250 mA while the secondary 5.0 V (VOUT2) is capable of supplying 100 mA.

Both outputs have a maximum dropout voltage of 600 mV and low reverse current.

Quiescent current drain is typically 150 mA when supplying 100 mA from each output.

The ENABLE input provides logic level
