6.9 Load Transient Response
Yellow = VOUT, DC coupled, Blue = Load Current, repetitive change between 50% (42.5mA) and 100% (85mA)
Figure 6-13 Load Transient Response, measured between TP6 and TP7 (a. no VOUT deviation observed due to the LDO; b. VOUT = 23V) 
Figure 6-14 Load Transient Response, measured between TP4 and TP5 (a. VOUT deviation between 24.2V and 24.7V; b. VOUT = 24.4V)
