■ General Description

The XC641A series are highly precise, low power consumption, multi power supply IC s, manufactured using CMOS and laser trimming technologies. The IC consists of a highly precise reference, 4 voltage regulators, 2 voltage detectors, and an output control circuit.

Because the regulators can be disabled through the EN pins, in standby, current consumption can be greatly reduced. The minimal input / output differential supports efficient voltage circuit design. The XC641A is particularly suitable for use with battery powered equipment where power supply control is all important.

The series comes in a small TSSOP-16 package.
