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
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
1. Working as a voltage regulator
2. 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.
