LM723 Voltage Regulators



National Semiconductor LM723 Voltage Regulators

TI's voltage regulators designed primarily for series regulator applications

Texas Instruments' LM723/LM723C are voltage regulators 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 fold-back 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.   LM723 Datasheet
