Voltage regulator

Diagram of the Voltage regulator

This regulator is capable of receiving and delivering maximum 40 volts to 0.5 volts at 37 amps and 2. The transistor 2N3055 is due to assemble in an appropriate heat sink.

The LM723/LM723C is a voltage regulator designed primarily for series regulator applications. By itself, it will supply output currents up to 150 mA; but external transistors can be added to provide any desired load current. The circuit features extremely low standby current drain, and provision is made for either linear or foldback current limiting.

The LM723/LM723C is also useful in a wide range of other applications such as a shunt regulator, a current regulator or a temperature controller.

The LM723C is identical to the LM723 except that the LM723C has its performance guaranteed over a 0°C to +70°C temperature range, instead of -55°C to +125°C.
