LT1790

Micropower SOT-23

Low Dropout Reference Family

FEATURES

DESCRIPTIO

The LT^®1790 is a family of SOT-23 micropower low

dropoutseriesreferencesthatcombinehighaccuracyand

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.

Sinks and Sources Current

Low Dropout Voltage

Guaranteed Operational –40°C to 125°C

Wide Supply Range to 18V

Available Output Voltage Options: 1.25V, 2.048V,

The LT1790s are ideally suited for battery-operated sys-

tems because of their small size, low supply current and

reduceddropoutvoltage.Thesereferencesprovidesupply

current and power dissipation advantages over shunt

referencesthatmustidletheentireloadcurrenttooperate.

Since the LT1790 can also sink current, it can operate as

a micropower negative voltage reference with the same

performance as a positive reference.
