Semtech SC728

2A Low Vin, Very Low Ron Load Switch

The SC728 is a low input voltage, very low Ron load switch designed for use in battery powered applications. Very low quiescent current of less than 2µA, and a low shutdown current of less than 1 µA (SC728) reduces power loss during Standby and Of states. A logic leve Enable allows low voltage on/of control down to 1.1V.
