3. Preventive measure against oscillation
For preventing the oscillation, it is advisable to use C4, the condenser of polyester film having small
characteristic fluctuation of the temperature and the frequency.
The resistance R to be series applied to C4 is effective for phase correction of high frequency, and improves the
oscillation allowance.

4. Junction temperature detecting pin(24)
Using temperature characteristic of a band gap circuit and in proportion to junction temperature, pin(24) DC
voltage: V2 rises at about + 10mV / °C temperature characteristic. So, the relation between V2 at Tj = 25°C and
V2x at Tj = x°C is decided by the following expression:

In deciding a heat sink size, a junction temperature can be easily
made clear by measuring voltage at this pin while a backside
temperature of IC was so far measured using a thermocouple type
thermometer.
