FEATURES
DESCRIPTION
The LM185-1.2 is a micropower 2-terminal band-gap
2
• Operating Current of 10μA to 20mA
voltage regulator diodes. Operating over a 10μA to
• 1Ω Maximum Dynamic Impedance (Typical)
20mA current range, it features exceptionally low
• Low Temperature Coefficient
dynamic impedance and good temperature stability.
On-chip trimming is used to provide tight voltage
• Radiation Qualified Option
tolerance. Since the LM185-1.2 band-gap reference
– 100 krad
uses only transistors and resistors, low noise and
– Low Dose Rate Tested at 10 mrad/s
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.
