Notes:

1. Efficiency measured at full load, at input voltage noted. Efficiency will be 2% lower if measured immediately after start-up.

2. Measured at 20MHz bandwidth, with noise probe directly across output terminals, and load terminated with 0.1µF ceramic and 10µF low ESR electrolytic

capacitors.
