DESCRIPTION/ORDERING INFORMATION  
The LT1009 reference circuit is a precision-trimmed 2.5-V shunt regulator featuring low dynamic impedance and  
a wide operating current range. The maximum initial tolerance is ±5 mV in the LP package and ±10 mV in the D  
and PW packages. The reference tolerance is achieved by 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 voltage to be adjusted  
±5% to eliminate system errors. In many applications, the LT1009 can be used as a terminal-for-terminal  
replacement for 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 used in applications such as  
digital voltmeters and current-loop measurement and control systems.  
The LT1009C is characterized for operation from 0°C to 70°C. The LT1009I is characterized for operation from  
–40°C to 85°C.
