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 control of the primary

output. With the primary output disabled, quiescent current drain is

typically 100

mA when supplying 100 mA from the secondary output.

The CS8481 is extremely robust with protection provided for

reverse battery, short circuit, overvoltage, and overtemperature on

both outputs.

The CS8481 is available in a D2PAK−5.
