GENERAL DESCRIPTION
The XC6406 series are highly precise, low power
consumption, dual positive regulators. They are fabricated
using Torex’s CMOS process. Performance features of the
series include high current and low dropout voltage, and the
series features a voltage reference, and error amplifier, a
current limiter and a phase compensation circuit plus a
driver transistor.
Output voltage of each regulator 1 and regulator 2 is
selectable in 100mV steps within the range of 1.8V to 6.0V.
The XC6406 series is available in the SOP-8 package.
