enough not to upset regulator function The LM723 compares a fraction the output voltage of the supply (obtained through the voltage divider of R 5, R6 and R 7) at pin 4 to that of the voltage reference, which is con nected to pin 5. If the output is too low the regulator supplies more output drive. and vice versa.

Jan 11, 2018 · In 1967 integrated circuit regulators were in their infancy, so the 723 requires a relatively high input voltage of between 9.4 and 40 volts to keep its internal 7.15 volt reference operating (see these and other handy figures on the first table on page three of the datasheet). High Voltage Step Down Regulator Typical Application Package: 8 pin SOIC with exposed thermal pad (suffix LJ) Description The A4447 is a 2 A, high efficiency general-purpose buck regulator designed for a wide variety of applications. The output voltage is adjustable from 0.8 to 24 V based on a resistor divider , and the 0.8 V ± 2 % reference. The datasheet is not very instructive on this, but the floating regulator variants will fail to regulate when the load resistance becomes to high. The load must be able to drain at least the supply current of the 723 circuit without exhibiting a voltage higher than the desired output voltage. LM723 was the bees knees voltage regulator controller and maybe also the only one readily available 'way back when'.
