description/ordering information
These micropower two-terminal band-gap voltage references operate over a 20-
A to 20-mA current range and
feature exceptionally low dynamic impedance and good temperature stability. On-chip trimming provides tight
voltage tolerance. The band-gap reference for these devices has low noise and long-term stability.
