9. REFERENCE: EXTERNAL CONNECTION EXAMPLES
9.10 Connection Example when Changing the Regulator Temperature Coefficient
as described in Section 5.3.
32
The temperature coefficient of the regulator is determined depending on that of the internal reference voltage
When setting the other temperature coefficient, use a thermistor resistor, etc. as shown in Fig.9.15.

Thermistor resistor :
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 Fig.9.15.
