n Low Profile (1mm) ThinSOT™ Package The LT®1790 is a family of SOT-23 micropower low dropout
series references that combine high accuracy and low drift
with low power dissipation and small package size. These
micropower references use curvature compensation to
obtain a low temperature coefficient and trimmed precision thin-film resistors to achieve high output accuracy. In
addition, each LT1790 is post-package trimmed to greatly
reduce the temperature coefficient and increase the output
accuracy. Output accuracy is further assured by excellent
line and load regulation. Special care has been taken to
minimize thermally induced hysteresis. n APPLICATIONS n n n Handheld Instruments …
