XC6406 Series
ETR0310_001
High Current Dual Positive Regulator
■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 increments within the range of 1.8V to 6.0V.
The XC6406 series is available in the SOP-8 package.
