P artial H eating
Caution Do not use different soldering methods together (except for partial heating).
(1) O bs erve precautions for handling becaus e of electro-s tatic s ens itive devices .
(2) F orm a ground pattern as widely as pos s ible to minimize ground impedance (to prevent undes ired os cillation).
(3) T he bypas s capacitor should be attached to V
(4) T he DC cut capacitor s hould be attached to Input and O utput pin.
T his product s hould be s oldered and mounted under the following recommended conditions .
(5) P in 1 (NC ) s hould be connected to the ground pattern.
S oldering Method
All the ground terminals mus t be connected together with wide ground pattern to decreas e impedance
difference.
