LM185-1.2/LM285-1.2/LM385-1.2  
Micropower Voltage Reference Diode  
The LM185-1.2 is rated for operation over a −55°C to 125°C  
temperature range while the LM285-1.2 is rated −40°C to 85°  
C and the LM385-1.2 0°C to 70°C. The LM185-1.2/LM285-1.2  
are available in a hermetic TO-46 package and the  
LM285-1.2/LM385-1.2 are also available in a low-cost TO-92  
molded package, as well as SO and SOT-23. The LM185-1.2  
is also available in a hermetic leadless chip carrier package.  
General Description  
The LM185-1.2/LM285-1.2/LM385-1.2 are micropower 2-ter-  
minal band-gap voltage regulator diodes. Operating over a  
10μA to 20mA current range, they feature exceptionally low  
dynamic impedance and good temperature stability. On-chip  
trimming is used to provide tight voltage tolerance. Since the  
LM185-1.2 band-gap reference uses only transistors and re-  
sistors, low noise and good long term stability result.  
Features  
Careful design of the LM185-1.2 has made the device excep-  
tionally tolerant of capacitive loading, making it easy to use in  
almost any reference application. The wide dynamic operat-  
ing range allows its use with widely varying supplies with  
excellent regulation.  
±1% and 2% initial tolerance  
Operating current of 10μA to 20mA  
dynamic impedance  
Low temperature coefficient  
The extremely low power drain of the LM185-1.2 makes it  
useful for micropower circuitry. This voltage reference can be  
used to make portable meters, regulators or general purpose  
analog circuitry with battery life approaching shelf life.  
Low voltage reference—1.235V  
2.5V device and adjustable device also available  
LM185-2.5 series and LM185 series, respectively  
Further, the wide operating current allows it to replace older  
references with a tighter tolerance part.
