It accepts an input up to 11.5 V and provides an adjustable output from 1.25 V up to 11 V, with a fixed 3.3 V option available. The 15 µA quiescent current makes it a fit for battery-powered or always-on circuits where every microamp counts. Control features include an enable pin and a low-battery detection comparator. Protection covers overcurrent, overtemperature, and reverse polarity — useful when the input supply is unpredictable.
Dropout and load — what the 200 mA rating means
The 0.64 V dropout at 200 mA is the voltage headroom needed between input and output at full load. Plan the input rail accordingly.
MSL level is not in the listing, so check the reel label or datasheet before reflow to avoid moisture-related popcorning.
No official second-source alternate is listed, but the fixed-output variant shares the same pinout and package.
