LM185/LM285/LM385 Adjustable Micropower Voltage References
General 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 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 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...
