Notes:

3. Start-up voltage operation is guaranteed with the addition of a Schottky B0520LW external diode between the input and output.

4. Steady-state output current indicates that the device maintains output voltage regulation under load.

5. Test condition for MSOP-8L and MSOP-10L: Devices mounted on 2oz copper, with minimum recommended pad layout on top and bottom

layer with thermal vias, double side FR-4 PCB.
