The LM117 is a positive linear voltage regulator. It can be programmed to produce a fixed output voltage using two resistors. This regulator is used as a case study to understand how:

- How types parameter distributions influence worst case performance
- The accuracy of a simulation model to mimic real part
- The ability of analysis tools to produce legitimate worst case results
