Typical Application
Figure 22. Typical Application of AP2122
Note: Filter capacitors are required at the AP2122's input and output. 1 µF capacitor is required at the input. The
minimum output capacitance required for stability should be more than 1 µF with ESR from 0.01Ω to 100Ω.
Ceramic capacitors are recommended.
