Notes:

5) Took the linear region (Current) measure Time1 at 20% and Time2 at 80% to calculate the base current rise and fall rate.

6) Evaluate on EVB.

7) Line Regulation = (VOUT @ VB=30V, 100uA load - VOUT @ VB=13V, 100uA load) / 12V * 100.

8) Load Regulation = (VOUT @ VB=30V, 40mA load - VOUT @ VB=30V,100uA load) / 12V * 100.

9) The dropout voltage is defined as VB -VOUT.

10) Guarantee by design.

11) Or force 5V and 0.5V on RT, then measure RT current.
