IC LM723 Voltage Regulator 37V/150mA

@ MODERN HALLROAD

The LM723CN is identical to the LM723 except that the LM723C has its performance ensured over a 0°C to +70°C temperature range, instead of −55°C to +125°C

The LM723 / LM723CN is also useful in a wide range of other applications such as a shunt regulator, a current regulator or a temperature controller.

IC LM723 is the adjustable voltage regulator IC designed for series regulator application, with a current output of 150mA without external pass transistor.

IC LM 723 / LM723CN is a voltage regulator designed primarily for series regulator applications.

The circuit features extremely low standby current drain, and provision is made for either linear or foldback current limiting.

If we use an transistor externally, it can able to provide up to 10A of current to drive any desired load up to this range.

The input supply is 40v maximum and its output voltage ranges from 3v to 40v. The IC 723 VOLTAGE REGULATOR is also used in various applications like shunt regulator, current regulator.

The IC 723 REGULATOR having low standby current drain, which allow us to use the IC as linear or fold back current limiting, with an operating temperature ranges from -55 °C to 150 °C.

The 723 voltage regulator is commonly used for series voltage regulator applications. It can be used as both positive and negative voltage regulator.

IC LM723 has an ability to provide up to 150 mA of current to the load, but this can be increased more than 10A by using power transistors. It also comes with comparatively low standby current drain, and provision is made for either linear or fold-back current limiting.

LM723 IC can also be used as a temperature controller, current regulator or shunt regulator and it is available in both Dual-In-Line and Metal Can packages.

The input voltage ranges from 9.5 to 40V and it can regulate voltage from 2V to 37V.

Another important point to note about this IC is that the supply voltage at the lowest point on the ripple waveform, should be at least 3 V greater than the output of the regulator and greater than Vref.
