• A higher heat radiation effect can be achieved by enlarging the copper laminate
• Obtaining the junction temperature
area connected to the inner frame to which a monolithic IC is mounted.
Measure GND terminal temperature T
this value in the following formula to obtain the junction temperature.

The output voltage may oscillate if a low ESR type capacitor
(such as a ceramic capacitor) is used for the output capacitor in
the SI-3000ZD Series.
The output voltage can be set by connecting R1 and R2 as shown
at left.
The recommended value for R2 is 10kΩ or 11kΩ.
