■PIN CONFIGURATION

* These contents are based on the result that evaluated the arbitrary sample. The characteristic is not guaranteed. The design and

reliability that fully considered flow mounting are checked but the influence by temperature profile etc. is also considered. Please consult

with sales representatives for a recommendation temperature profile.

The NJM2820/ 2821/ 2822 is a 1.25V precision shunt

regulator.

High precision voltage accuracy of ±0.7%* is realized by

the total optimization from chip design to packaging. In

addition, it features low cathode current of 80uA for low

current operation.

It is suitable for AC-DC converter secondary circuit,

reference voltage applications for A/D and D/A converters,

and other applications where precision reference is required.
