Low Dropout Reference Family
DESCRIPTIO
The LT
dropout series references that combine high accuracy and
low drift with low power dissipation and small package
size. These micropower references use curvature com-
pensation to obtain a low temperature coefficient and
trimmed precision thin-film resistors to achieve high
output accuracy. In addition, each LT1790 is post-pack-
age 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.
The LT1790s are ideally suited for battery-operated sys-
tems 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.
