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 stand-
by, 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.
