DESCRIPTIO
The LT
ence combined with a 7V auxiliary reference. The 1.2V/2.5V
reference is a trimmed, thin-film, band-gap, voltage refer-
ence with 1% initial tolerance and guaranteed 20ppm/ C
temperature drift. Operating on only 20 A, the LT1034
offers guaranteed drift, low temperature cycling hyster-
esis and good long-term stability. The low dynamic im-
pedance makes the LT1034 easy to use from unregulated
supplies. The 7V reference is a subsurface zener device for
less demanding applications.
The LT1034 reference can be used as a high performance
upgrade of the LM385 or LT1004, where guaranteed
temperature drift is desired.
