Notes:

4. Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its

6. Test condition for DFN3030E-8: Device mounted on 2"x2", FR-4 substrate PCB, with minimum recommended pad on top layer

and thermal vias to bottom layer ground plane.
