Input Decoupling Capacitor (C1)
input line is long and has high impedance or if more stable
operation is needed, input capacitor C1 should be connected
as close as possible to the IC. Recommended range of input
capacitor value is 100 nF to 10 mF.
Output Decoupling Capacitor (C2)
but if faster response and higher stability reserve is needed,
output capacitor should be connected as close as possible to
the device. Recommended range of output capacitance is
100 nF to 10 mF. Larger values of output capacitance and
lower ESR improves dynamic parameters.

voltage would be unstable or indefinite and unexpected

Thermal
necessary to provide some thermal relief. The maximum
power dissipation supported by the device is dependent
upon board design and layout. Mounting pad configuration
on the PCB, the board material, and also the ambient
temperature affect the rate of temperature increase for the
part. When the device has good thermal conductivity
through the PCB the junction temperature will be relatively
low in high power dissipation applications.
stops operation of regulator, if junction temperature is
higher than 150°C. After that, when junction temperature
decreases below 125°C, the operation of voltage regulator
would restart. While high power dissipation condition is, the
regulator starts and stops repeatedly and protects itself
against overheating.
PCB layout
number 2, 4 and 5 of SOIC6−TL must be wired to the GND
plane while it is mounted on board. Make VIN and GND
lines sufficient. If their impedance is high, noise pickup or
unstable operation may result. Connect capacitors C1 and
C2 as close as possible to the IC, and make wiring as short
as possible.
As a power across the IC increase, it might become
