FEATURES  
DESCRIPTIO  
Tight Initial Output Voltage: <0.05%  
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  
very low TC and tight initial output voltage tolerance.  
Ultralow Drift: 3ppm/°C Typical  
Series or Shunt Operation  
Curvature Corrected  
Ultrahigh Line Rejection: 0.5ppm/V  
Low Output Impedance: 0.02Ω  
Plug-In Replacement for Present References  
Available at 2.5V, 4.5V, 5V, and 10V  
100% Noise Tested  
Temperature Output  
Industrial Temperature Range in SO-8  
Available in 8-Lead N8 and S8 Packages  
The LT1019 can both sink and source up to 10mA and can  
be used in either the series or shunt mode, allowing the  
reference to operate with positive or negative output  
voltages without external components. Minimum input/  
outputvoltageislessthan1Vintheseriesmode,providing  
improved tolerance of low line conditions and excellent  
line regulation.  
U
APPLICATIO S  
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.
