DESCRIPTIO

ence. Operating with supplies from 1.4V up to 18V, the

device draws only 5.6

µA typical, making it ideal for low

voltage systems as well as handheld instruments and

industrial control systems. With only two resistors the

internal buffer amplifier can scale the 400mV reference to

any desired value up to the supply voltage.

The reference is postpackage-trimmed to increase the

output accuracy. The output can sink and source 200

µA

over temperature. Quiescent power dissipation is 28

µW.

Stability is ensured with any output capacitor of 1

µF or

higher.

The LT6650 is the lowest voltage series reference available

in the 5-lead SOT-23 package.
