LT1790

Micropower SOT-23

Low Dropout Reference Family

FEATURES

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 coefﬁcient and trimmed preci-

sion 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.

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 sup-

ply 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.
