ACT4088 Optimized for Minimal External Components

The ACT4088 with provides excellent AC and DC results across a wide range of external component combinations. The circuit of

Figure 3 can be used to generate a 5V output from a 12V input utilizing a smaller (i.e. lower-cost) output capacitor while maintaining

good performance.
