PROBLEM TO BE SOLVED: To provide a reference voltage supply circuit and electronic apparatus, capable of supplying a stable reference voltage when power supply starts up.SOLUTION: The reference voltage supply circuit includes a reference voltage generation section 10 that generates a reference voltage divided by a resistor from a power voltage and a differential amplification section 20 that performs differential amplification from an input reference voltage and an output voltage output to FET. When its configuration is made so that a voltage input into the FET exceeds a reference value, a Zener diode DZ that limits the voltage input into the FET is provided. |
