Vin=53 V, Io=80A resistive load.
Band width=4MHz.
Time scale: 2s / div.
Output voltage response to load current step-change
(20-60-20 A) at TC=+25 °C, Vin=53 V.
Trace: output voltage (420mV/div.).
dI/dt = 4 A/s
Time scale: 100 s/div.

Output Voltage Adjust
The resistor value for an adjusted output voltage is calcu-
lated by using the following equations:
Output Voltage Adjust Upwards, Increase:
Radj= [(VO(100+
%)/(1.225%))-(100+2%)/%] k
Output Voltage Adjust Downwards, Decrease:
Radj= [100 /
%-2] k
Ex. Increase 5% to: 2.625 Vdc
(2.5(100+5)/(1.225*5)-(100+2*5)/5 = 21 kOhm
Ex. Decrease 5% to: 2.375 Vdc
(100/5)-2= 18 kOhm
