Figure 15. Increasing Output Voltage by Cascading Devices

It is possible to regulate the output of the LM2665 by use of a low dropout regulator (such as LP2980-5.0). The

whole converter is depicted in Figure 16.

A different output voltage is possible by use of LP2980-3.3, LP2980-3.0, or LP2980-adj.

Note that, the following conditions must be satisfied simultaneously for worst case design:
