LM185 / LM285 / LM385可调微功耗电压基准 LM185/LM285/LM385 Adjustable Micropower Voltage References
DESCRIPON
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 almost any reference application. The wide dynamic operating range allows its use with widely varying supplies with excellent regulation.
FEATURES
• Adjustable from 1.24V to 5.30V
• Operating Current of 10μA to 20mA
• 1% and 2% Initial Tolerance
