Thermal design
Refer to the following thermal derating curves (Fig. 25, 26), when using in the status of Ta=25℃ or more.
The characteristic of IC is greatly related to the operating temperature.
When it is used in over maximum junction temperature, the elements inside IC might become weaker and be destroyed.
It is recommended to take into consideration thermal of IC.
Note that the temperatures are in the allowed temperature limits and operated within Pd.
It is necessary to operate it at junction temperature Tjmax or less to prevent IC from the thermal destruction.
Please operate IC within permissible loss Pd because the junction temperature Tj might become considerably a high
temperature even if ambient temperature Ta is normal temperature (25℃).
Power consumption Pc(W) may be expressed by the equation shown below:
Pc=(Vin-Vo)×Io+ Vin×Iｂ
permissible loss Pd≧Pc
Maximum Output current IoMAX can be calculated in thermal design.
·
Calculation example
Ex.1) Ta=85℃, Vin =7.5V, Vo=5.0V
Io≦400ｍA
Be sure to use this IC within a power dissipation at the range of operating temperature.

Terminal Setting and Cautions
·
INPUT
It is recommended that a capacitor (about 0.33uF) be inserted between INPUT and COMMON.
The value of capacitor is designed suitable for the actual application.
·
OUTPUT
It is recommended that a capacitor (about 0.1uF) be inserted between OUTPUT and COMMON.
A tantalum capacitor can also be used for this pin because insufficient capacitors may cause oscillation by a temperature
change.
·
COMMON
Keep the no voltage drop between Ground level of set board and IC.
When there is the voltage difference, setting voltage becomes inaccuracy and unstable.
It is recommended to connect by wide, short pattern, and lower the inpedance.
