ZRT100
9.8V LOW POWER PRECISION REFERENCE SOURCE
DESCRIPTION
The ZRT100 is a m onolithic integrated circuit providing
a precise stable reference voltage of 9.8V at 500µA.
The circuit features a knee current of 150µA and
operation over a wide range of tem peratures and
currents.
The ZRT100 is available in a SOT223 package for
surface m ount applications. This device offers a trim
facility whereby the output voltage can be adjusted as
s h o w n in Fig .1 . Th is fa c ilit y is u s e d w h e n
co m p e n s a tin g fo r s ys te m e rro rs o r s e ttin g th e
reference output to a particular value. When the trim
facility is not used, the pin should be left open circuit.
SOT223
FEATURES
• Trim m able output
• Excellent tem perature stability
• Low output noise figure
