(see Note 1)

1) The load transition was measured as the voltage drop at the drain of Q1

(see Figure 1–2). Therefore load on is displayed as 0 V and load off is
displayed as 3.3 V.

2) In order to display the output voltage transient with high resolution, a dc

offset of 3.3 V was introduced. The actual dc values can be seen with the
cursor lines in Figure 4–5.
output voltage without full load: 3.296 V
output voltage with full load: 3.278 V
