National P/N LM385-1.2 - Micropower Voltage Reference Diode
The LM185-1.2/LM285-1.2/LM385-1.2 are micropower 2-terminal band-gap voltage regulator diodes.
Operating over a 10 A to 20 mA 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.
