The MAX882CSA+ from Analog Devices is a positive-output linear regulator delivering up to 200 mA. 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.
Temperature grade and package
Rated for 0°C to 70°C commercial temperature range, this part is suited for indoor, office, or consumer equipment — not for an engine bay or outdoor enclosure. The 8-SOIC package (3.90 mm body width) is a standard surface-mount footprint that places cleanly on a pick-and-place line. MSL level is not in the listing, so check the reel label or datasheet before reflow to avoid moisture-related popcorning.
Lifecycle and sourcing
The MAX882CSA+ carries an active lifecycle status and is ROHS3 compliant. No official second-source alternate is listed, but the fixed-output variant shares the same pinout and package.
