APPLICATIONS INFORMATION
Figure 1 shows the basic hookup diagram for fixed-voltage
models. All models require an output capacitor for proper
operation and to improve high frequency load regulation. A
10
μ
F tantalum capacitor is recommended. Aluminum elec-
trolytic types of 50
μ
F or greater can also be used. A high
quality capacitor should be used to assure that the ESR
(Effective Series Resistance) is less than 0.5
.
Figure 2 shows a hookup diagram for the adjustable voltage
model. Resistor values are shown for some commonly used
output voltages. Values for other voltages can be calculated
from the equation shown in Figure 2. For best load regula-
tion, connect R
1
close to the output pin and R
2
close to the
ground side of the load as shown.
