Careful design of the LM185-1.2-N has made the
1FEATURES device exceptionally tolerant of capacitive loading,
2• ±1% and 2% Initial Tolerance making it easy to use in almost any reference
• Operating Current of 10μA to 20mA application. The wide dynamic operating range allows
its use with widely varying supplies with excellent
• 1ΩDynamic Impedance regulation.
• Low Temperature Coefficient The extremely low power drain of the LM185-1.2-N
• Low Voltage Reference—1.235V makes it useful for micropower circuitry. This voltage
• 2.5V Device and Adjustable Device Also reference can be used to make portable meters,
Available regulators or general purpose analog circuitry with

respectively Further, the wide operating current allows it to
replace older references with a tighter tolerance part.
DESCRIPTION The LM185-1.2-N is rated for operation over a −55°C
The LM185-1.2-N/LM285-1.2-N/LM385-1.2-N are to 125°C temperature range while the LM285-1.2-N is
micropower 2-terminal band-gap voltage regulator rated −40°C to 85°C and the LM385-1.2-N 0°C to
diodes. Operating over a 10μA to 20mA current 70°C. The LM185-1.2-N/LM285-1.2-N are available in
range, they feature exceptionally low dynamic a hermetic TO package and the LM285-1.2-N/LM385-
impedance and good temperature stability. On-chip 1.2-N are also available in a low-cost TO-92 molded
trimming is used to provide tight voltage tolerance. package, as well as SOIC and SOT-23.
Since the LM185-1.2-N band-gap reference uses only
transistors and resistors, low noise and good long
term stability result.

(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
