2.5-V INTEGRATED REFERENCE CIRCUIT Excellent Temperature Stability •
Wide Operating Current Range Initial Tolerance: 0.2% Max •
Directly Interchangeable With LM136 Dynamic Impedance: 0.6Ω Max •
Needs No Adjustment for Minimum
Temperature CoefficientThe LT1009 reference circuitisa precision-trimmed 2.5-V shunt regulator featuring low dynamic impedance and wide operating current range. The maximum initial toleranceis±5 mVin the LP package and ±10 mVin theD
and PW packages. The reference toleranceis achievedby on-chip trimming, which minimizes the initial voltage
tolerance and the temperature coefficient, αVZ.
Although the LT1009 needs no adjustments,a third terminal (ADJ) allows the reference voltageto be adjusted
±5%to eliminate system errors.In many applications, the LT1009 can be used asa terminal-for-terminal
replacementfor the LM136-2.5, which eliminates the external trim network.
The LT1009 uses include 5-V system references, 8-bit analog-to-digital converter (ADC) and digital-to-analog
converter (DAC) references, and power-supply monitors. The device also can be usedin applications suchas
digital voltmeters and current-loop measurement and control systems.
