Use 7815 and 7915 according to the chip manual to access the circuit voltage regulator output greater than 15V?
7815 is the output 15V, 7915 is the output -15V, and the input voltage is greater than the output voltage. V (this data is noted in the manual), the input voltage has a ripple that you can improve by increasing the capacitance, but not eliminate.
