XC6406
Series
High Current Dual Positive Regulator
ETR0310_001
■GENERAL
DESCRIPTION
The XC6406 series are highly precise, low power consumption, dual positive regulators.
CMOS process.
They are fabricated using Torex’s
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.
