3D Model
It is an adjustable voltage regulator which operates in both positive or negative supply operation.
Voltage can be adjusted from 2V to 37V.
The maximum input voltage is 40V.
Output current is 150mA without an external pass transistor. It can be increased to 10A by adding transistors externally.
It has a low standby current gain, very low-temperature drift, and high ripple rejection.
The load and line regulation is 0.03% and 01%.
It has a built-in fold back current limiting.
Its performance is ensured over -55 °C to +125 °C.

Basic high and low voltage regulators can be designed by connecting appropriate external components with this IC.
Linear, switching and floating regulators.
Series and shunt regulators.
Basic Low Voltage Regulator (VO = 2 to 7V)
Basic High Voltage Regulator (VO = 7 to 37V)
LM723 is an adjustable voltage regulator used for shunt regulator, current regulator, and temperature controller. It can able to provide a higher range of output voltage and current up to 10A by simply adding a series pass transistor with it, with having a wider range of operating temperature so the IC able to withstand for long. Also, it is able to use as either linear or switching type regulator. But this IC is specially designed for series regulator application.
To use this IC for the different range of required output voltage, you can proceed with various circuits available in LM723 datasheet with having your needed output range. For getting an output voltage range from 2v to 7v you can use the circuit below, which is a Basic Voltage Regulator circuit using LM723 voltage regulator IC.
To find the value of resistance R3 you can use the formula below:
R3 = (R1*R2) / (R1+R2)
You can adjust the voltage by using the potentiometer in the circuit to get the required regulated output voltage. For finding the value of output voltage for this circuit you can use the formula below:
Vout = Vref * (R2 / R1 + R2)
