The LM723/LM723C is a voltage regulator designed primarily for series regulator applications. It can supply output currents up to 150 mA by itself, and 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.
The document is a technical datasheet for the LM723/LM723C voltage regulator manufactured by National Semiconductor. It describes the device as designed primarily for series regulator applications but also useful in shunt regulation, current regulation, and temperature control. The LM723C variant offers performance guarantees over a 0°C to +70°C range compared to the standard LM723.
