... Switch with 3.3V Supply Generation The MIC2582/83 can be configured to switch a primary supply while generating a secondary regulated voltage rail. The circuit in Figure 8 enables the MIC2582 to switch a 5V supply while also providing a 3.3V low dropout regulated supply with only a few added external components. Upon enabling the MIC2582, the GATE output voltage increases and thus the 3 ...
