The

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 package. The reference tolerance is achieved  
by on-chip trimming, which minimizes the initial  
voltage tolerance and the temperature

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 ADC and 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.
