Datasheet for the LM336-2.5V, a precision 2.5 V shunt voltage reference diode with an adjust pin for trimming the voltage and minimizing temperature drift. The 177 KB PDF covers pinout across packages, operating current range, tolerance, temperature coefficient and typical circuits. In repairs it helps confirm the reference in meters, ADC circuits and regulators sits at the right voltage, check the bias resistor provides adequate current, and select a correct substitute when the reference has drifted.
