APPLICATION HINTS
When using these circuits, please be sure to observe the
following points:
Phase compensation is made for securing stable operation
even if the load current varies. For this reason, be sure to
use a capacitor C
OUT
with good frequency characteristics
and ESR (Equivalent Series Resistance) as described in
the graphs on page 11.
On page 11, the relations between I
OUT
(Output Current)
and ESR of Output Capacitor are shown. The conditions
where the white noise level is under 40 V (Avg.) are
marked by the shaded area in the graph. (note: When
additional ceramic capacitors are connected to the Output
Pin with Output capacitor for phase compensation, there
is a possibility that the operation will be unstable. Because
of this, test these circuits with as same external
components as ones to be used on the PCB).

Please be sure the V
in
and GND lines are sufficiently
wide. When the impedance of these lines is high, there is
a chance to pick up noise or to malfunction.
Connect the capacitor with a capacitance of 1.0 F or
more between V
in
and GND as close as possible to V
in
or
GND.
Set external components, especially the Output Capacitor,
as close as possible to the circuit, and make the wiring as
short as possible.
