LT1019
Precision Reference
The LT
1019 is a third generation bandgap voltage refer-
ence utilizing thin film technology and a greatly improved
curvature correction technique. Wafer level trimming of
both reference and output voltage combines to produce
units with high yields to very low TC and tight initial
tolerance of output voltage.
The LT1019 can both sink and source up to 10mA and can
be used in either the series or shunt mode. This allows the
reference to be used for both positive and negative output
voltages without external components. Minimum input/
output voltage is less than 1V in the series mode, providing
improved tolerance of low line conditions.
The LT1019 is available in four voltages: 2.5V, 4.5V, 5V
and 10V. It is a direct replacement for most bandgap
references presently available including AD580, AD581,
REF-01, REF-02, MC1400, MC1404 and LM168.
