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.
