How does a LM723 work?
LM723 IC is a changeable voltage regulator, used in the series regulator application with 150mA current o/p without exterior pass transistor. When we utilize an external transistor, then it supplies 10A current to drive the load. The input voltage supply is maximum 40V & its o/p voltage ranges from 3volts to 40volts.
What is LM723?
The LM723/LM723C is a voltage regulator designed. 2• 150 mA Output Current Without External Pass. primarily for series regulator applications. By itself, it. Transistor.
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 are applications of voltage regulators state working of voltage regulator ic723?
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.
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.
What is Zener diode used for?
Zener diodes are used for voltage regulation, as reference elements, surge suppressors, and in switching applications and clipper circuits. The load voltage equals breakdown voltage VZ of the diode. The series resistor limits the current through the diode and drops the excess voltage when the diode is conducting.
What is the disadvantage of IC 723?
Reducing Dissipation in IC 723 Power Supply Circuit While using chip 723 in a low-voltage high-current mode, through an outer series transistor working through the existing power supply lines used by the IC 723, usually leads to abnormal heat dissipation on the series external transistor.
What are the five application of Zener diode?
What can an IC LM723 be used for?
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.
What is the voltage of the LM723 circuit?
LM723 compares the voltage of the non-inverting pin with a voltage of inverting pin and provides output voltage/current according to the above formula. This example circuit provides variable output in the range of 2.6-24V. It can provide 1 Ampere output load current.
What is the input voltage of an IC LM 723 voltage regulator?
The input voltage ranges from 9.5 to 40V and it can regulate voltage from 2V to 37V. The internal working can be explained by dividing it into two blocks, the reference voltage generator and the error amplifier.
