Typical Applications
Figure 1. Fixed Output Regulator
Figure 2. Constant Current Regulator
Notes:
1. To specify an output voltage, substitute voltage value for "XX"
2. Although no output capacitor is needed for stability, it does improve transient response.
3. CI is required if regulator is located an appreciable distance from power Supply filter
