The Maxim MAX6006BESA+ is a precision shunt voltage reference delivering a fixed 1.25 V output with ±0.5% initial tolerance. As a shunt (two-terminal) reference, it behaves like a Zener diode — you bias it with a series resistor from a higher supply rail, and it regulates the voltage across itself by sinking current through the cathode. The 1 µA minimum cathode current means it can operate from very low bias currents, making it suitable for battery-powered or micropower analog circuits where every microamp counts.

Frequently asked questions
What is the closest pin-compatible alternative to MAX6006BESA+?
The MAX6006ESA+ (without the 'B' suffix) is the same part with a looser ±1% tolerance instead of the ±0.5% grade. It is pin-compatible and functionally identical, so it can serve as a drop-in replacement if the tighter tolerance is not required.
