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 COUT with good frequency characteristics
and ESR (Equivalent Series Resistance) as described in
the graphs on page 11.
On page 11, the relations between IOUT (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 Vin 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 Vin and GND as close as possible to Vin or
GND.
Set external components, especially the Output Capacitor,
as close as possible to the circuit, and make the wiring as
short as possible.
