Electrical Characteristics
Electrical characteristics are guaranteed over the full junction temperature range (0-105
°
C). Ambient temperature must be derated
based upon power dissipation and package thermal characteristics. Unless otherwise stated, test conditions are: V

= V
REF
, VCC=5V
and I
OUT
= 1 mA.

*Temperature deviation is defined as the maximum deviation of the reference over the given temperature range and does not imply an
incremental deviation at any given temperature.
