The MIC2950 is available as either an -05 or -06 version.

The -05 and -06 versions are guaranteed for junction

temperatures from –40°C to +125°C; the -05 version has

a tighter output and reference voltage specification

range over temperature. The MIC2951 is available as an

-02 or -03 version.

The MIC2950 and MIC2951 have a tight initial tolerance

(0.5% typical), a very low output voltage temperature

coefficient which allows use as a low-power voltage

reference, and extremely good load and line regulation

(0.04% typical). This greatly reduces the error in the

overall circuit, and is the result of careful design

techniques and process control.
