CS8481 Datasheet, PDF (1/6 Pages) ON Semiconductor – 3.3 V/250 mA, 5.0 V/100 mA Micropower Low Dropout Regulator with ENABLE

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 (V_OUT1) supplies up to
250 mA while the secondary 5.0 V (V_OUT2) 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.
