A. R
SET
required to set the output voltage to a value higher than 0.69 V. See the Electrical Characteristics table.
B. 200 μF of output capacitance can be achieved by using two 100-μF ceramic capacitors or four 47-μF ceramic
capacitors.
C. 300 µF of ceramic or 330 µF of electrolytic input capacitance is required for proper operation.
D. For V
I
greater than 8 V, the minimum required C
I
may be reduced to 200 µF ceramic or 220 μF electrolytic plus a
22-μF ceramic capacitor.
