ADJUSTABLE HIGH PRECISION SHUNT REGULATOR

■GENERAL DESCRIPTION

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.
