1 Original Creation Date: 08/31/95 Last Update Date: 10/13/03 Last Major Revision Date: 10/02/03 PRECISION VOLTAGE REGULATOR General Description The LM723 is a voltage regulator designed primarily for series regulator applications. By itself, it will supply output currents up to 150mA, 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 is also useful in a wide range of other applications such as a shunt regulator, a current regulator or a temperature controller.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number given in the Absolute Maximum Ratings, whichever is lower.
