9. REFERENCE: EXTERNAL CONNECTION EXAMPLES
9.10 Connection Example when Changing the Regulator Temperature Coefficient
The temperature coefficient of the regulator is determined depending on that of the internal reference voltage as
described in Section 5.3.
When setting the other temperature coefficient, use a thermistor resistor, etc. as shown in Figure 9.15.

Power-off method
Set the POFF1X pin to level LOW (VI); all circuits will be turned off.
Regulator temperature coefficient
For information about the basic regulator setting method and notes, see Section 5.4.
The temperature characteristics of the thermistor resistor RT indicate the nonlinearity. When
compensating the linear characteristics, insert the RP shown in Figure 9.15.
Other setting conditions
(1) When using the high output mode
Connect the FC pin to VI.
