Reference VoltageTypical ApplicationNote: Ci is required when regulator is located an appreciable distance from power supply filter. Note: Co is not needed for stability, however, it does improve transient response. Note: Since IADJ is controlled to less than 100PA, the error associated with this term is negligible in most applications. FIGURE 5. Programmable Regulator 3 www.fairchildsemi.com
