GENERAL DESCRIPTION

The XCM406A series is a high current, dual LDO regulator in an ultra small USP-12B01 package which measures just 2.8mm x

2.3mm. 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 0.05V 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.
