XCM406 Series
ETR2406-003
High Current High Speed Dual LDO Regulator
˙GENERAL DESCRIPTION
The XCM406 series is a high current, dual LDO regulator in an ultra small USP-12B01 package which measures just 2.8mm x
2.8mm. The IC is basically two XC6210 high speed CMOS LDOs which are precise, low noise, high current, regulators
consisting of a voltage reference, an error amplifier, a current limiter and phase compensation circuit plus a driver transistor. The
low ON resistance of the built-in driver transistor means that batteries can be used to a minimal input-output voltage differential
and can therefore be used for a longer time. The series can be used with low ESR ceramic capacitors and output voltages are
selectable in 0.1V increments within a range of 0.8V to 5.0V per channel. The fold-back current limit circuit also operates as the
output current limiter and the output pin protector.
The IC can be placed in stand-by mode via the CE function so that power consumption is greatly reduced.
