    1О© Dynamic Impedance
    Low Temperature Coefficient DESCRIPTION
    The LM185/LM285/LM385 are micropower 3-terminal
    adjustable band-gap voltage reference diodes.
    Operating from 1.24 to 5.3V and over a 10ОјA 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 band-gap reference uses
    only transistors and resistors, low noise and good
    long-term stability result. Careful design of the LM185 has made the device
    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 makes it
    useful for micropower circuitry. This voltage reference
    can be used to make portable meters, regulators or ...
