DESCRIPTION

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 coeffi cient and trimmed preci­sion thin-fi lm resistors to achieve high output accuracy. In
addition, each LT1790 is post-package trimmed to greatly
reduce the temperature coeffi cient 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.

The LT1790s are ideally suited for battery-operated sys­tems because of their small size, low supply current and
reduced dropout voltage. These references provide sup­ply current and power dissipation advantages over shunt
references that must idle the entire load current to operate.
Since the LT1790 can also sink current, it can operate as
a micropower negative voltage reference with the same
performance as a positive reference.
