NOTES: A. The device requires a minimum of 9 V between VCC+ and VCC– when VO is equal to or more positive than –9 V.
B. When 10-lead
μ
A723U devices are used in applications requiring VZ, an external 6.2-V regulator diode must be connected in series
with OUTPUT.
C. L is 40 turns of No. 20 enameled copper wire wound on Ferroxcube P36/22-3B7 potted core or equivalent, with a 0.009-inch air gap.
