Which type of regulator is IC 723?
The 723 voltage regulator is commonly used for series voltage regulator applications. It can be used as both positive and negative voltage regulator. It 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.
How many pins are there in IC 723?
It consists of a voltage reference source (Pin 6), an error amplifier with its inverting input on pin 4 and non-inverting input on pin 5, a series pass transistor (pins 10 and 11), and a current limiting transistor on pins 2 and 3.
What is the IC 723?
Explanation: The IC 723 is a voltage regulator, which can act as both a low voltage regulator as well as a high voltage regulator. Output can be set between 7-37 volts. 7 volts is the reference starting voltage.
Which connection is used in IC 723 to boost the current?
Due to this reason output terminal pin10 of the IC 723 is upgraded with an external emitter follower transistor Tr1. This allows the IC output to get upgraded to much higher current depending on the rating of the transistor.
