LT1790

Micropower SOT-23

Low Dropout Reference Family

FEATURES

DESCRIPTION

The

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

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.
