General Description
The LM185-1.2/LM285-1.2/LM385-1.2 are micropower 2-terminal 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 resistors, low noise and
good long term stability result.
Careful design of the LM185-1.2 has made the device exceptionally tolerant of capacitive loading, making it easy to use in
almost any reference application. The wide dynamic operating range allows its use with widely varying supplies with excellent
regulation.
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.
Further, the wide operating current allows it to replace older references with a tighter tolerance part.
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.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
