700mA High Speed Dual LDO Regulator
ETR2406-004b
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.

Care must be taken for an electrical potential of each dissipation pad so as to enhance mounting strength and heat release when the pad
needs to be connected to the circuit.
