DESCRIPTION

The TS821 is a micropowerintegrated circuit which

is a high stability, two terminals, band gap refer-

ence providing a stable output voltage over the in-

dustrial temperature range (-40 to +85oC). The

minimum operating current is guaranteed at 50µA

over the full operating temperature range.
