Typical Application

Figure 5. Programmable Regulator

Ci is required when regulator is located an appreciable distance from power supply filter.

Co is not needed for stability, however, it does improve transient response.

Since IADJ is controlled to less than 100µA, the error associated with this term is negligible in most applications.
