XCM406 Series

Dual High Speed LDO Regulator

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 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.

FAQ

QuestionWhat is the standby current?
Answer

The current that flows through the IC in the standby mode. The standby mode means the state where the IC has been turned off by the CE function.
