The 723 is a monolithic precision voltage regulator constructed on a single silicon chip. The device consists of a temperature compensated reference, error amplifier, power series pass transistor and current limit circuitry. Some of its important features - adjustable output voltage from 2 to 37V, of either polarity, 0.01% line and 0.03% load regulation, output current upto 150mA without external pass transistor make it a general purpose IC for voltage or current regulation.
The experimental set-up consists of an IC 723 with facilities for convenient connections, an unregulated power supply, voltmeter, an ammeter and all the other components - resistances, potentiometers, variable load etc. required to perform the experiments.
The following studies can be carried out :
- Working as a voltage regulator
- Working as a current regulator
The above experimental set-up has been laid down on a decorated bakelite board with an aim of providing an easy understanding to the students. All components are well spread out for clarity and easy repairs and replacement. The set-up is provided with a booklet, which contains its detailed theory of operation, description, specifications, suggestions and discussion on the various experiments that may be performed with it
The set-up is complete in all respect, including patch chords.
