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 …
