The Analog Devices MAX882CSA+T is a positive adjustable linear voltage regulator delivering up to 200 mA from a 1.25 V to 11 V output range. It operates from an input up to 11.5 V and draws only 15 µA quiescent current, making it a fit for battery-powered instrumentation, portable equipment, and low-power industrial control boards where thermal budget and standby efficiency matter. The 8-SOIC package suits surface-mount assembly on mixed-signal PCBs.
The 15 µA quiescent current (25 µA supply maximum) is the headline efficiency spec. Compare that to a generic 78xx-type linear regulator that pulls several milliamps just to bias itself — the MAX882CSA+T keeps the idle draw under control without needing a downstream load-switch to disconnect it.
Built-in over-current, over-temperature, and reverse-polarity protection cover the common fault conditions a board-level regulator sees. The Enable pin lets a microcontroller or supervisor gate the output, and the Low-Battery Detection output provides a flag when the input rail drops below a programmed threshold — useful for early-warning shutdown in battery-backed designs.
It belongs in office equipment, benchtop instruments, consumer electronics, and indoor industrial enclosures — not in an engine bay, outdoor telecom cabinet, or freezer. For extended-temperature builds, look at the industrial-grade siblings in the same family.
