1790 TA01
2.5V Micropower SOT-23
Low Dropout Reference
March 2000
The LT
1790-2.5 is a SOT-23 micropower low dropout
series reference that combines high accuracy and low drift
with low power dissipation and small package size. This
micropower reference uses curvature compensation to
obtain a low temperature coefficient and trimmed preci-
sion thin-film resistors to achieve high output accuracy. In
addition, the LT1790-2.5 uses post-package trimming 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.
The LT1790-2.5 is ideally suited for battery-operated
systems because of its small size, low supply current and
reduced dropout voltage. This reference provides supply
current and power dissipation advantages over shunt
references that must idle the entire load current to operate.
However, since the LT1790-2.5 can also sink current, it
can operate as a micropower negative voltage reference
with the same performance as a positive reference.
