What is IC 79xx?
IC 79xx is a three-pin negative voltage controller IC. It is a small integrated circuit used in a circuit to supply a constant negative input voltage.
Where 78xx IC are used?
electronic circuits
78xx (sometimes L78xx, LM78xx, MC78xx…) is a family of self-contained fixed linear voltage regulator integrated circuits. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost.
What are meant by IC 78xx and IC 79xx?
78xx voltage regulator ICs produce positive fixed DC voltage values, whereas, 79xx voltage regulator ICs produce negative fixed DC voltage values. Both 78xx and 79xx voltage regulator ICs have 3 pins each and the third pin is used for collecting the output from them.
How many terminals 79xx series IC regulator have?
The 79xx series of voltage regulators are the usually used negative voltage regulators. They are three terminal regulators and is available with fixed output voltages of -5V, -12V and -15V.
How many terminals does a 79XX series IC regulator have Mcq?
Voltage Regulators MCQ Question 3 Detailed Solution. Fixed-Negative Voltage Regulator: The series 79XX regulators are the three-terminal IC regulators that provide a fixed negative output voltage.
What is lm in LM741 IC?
LM stands for “linear monolithic”, a series of ICs originally produced by National Semiconductor which put a number of analog components together into a single piece of silicon.
What are 79xx series ICs?
79xx Features Series of ICs. Pinout Diagram of 79xx Series ICs. The Linear voltage regulators are components with or without associated circuitry which provide a stabilized output voltage from a potentially unstable power supply source.
What is the function of IC 79xx voltage regulator?
79xx voltage regulators are very commonly used in electronic circuits. The main purpose of this IC is to supply required regulated negative voltage to the circuits. IC 79xx can supply a constant negative voltage output, in spite of any voltage fluctuations in its input voltage.
What is the difference between LM317 and 79xx series of voltage regulators?
And 79xx series of voltage regulators perform in pretty much the same way but they are intended to output a negative voltage. LM317 provides an adjustable technique filling the gap where the fixed voltage regulator isn’t available or a variable voltage supply is required.
What is the function of IC 7912?
This is the IC 7912. 79xx voltage regulators are very commonly used in electronic circuits. The main purpose of this IC is to supply required regulated negative voltage to the circuits. IC 79xx can supply a constant negative voltage output, in spite of any voltage fluctuations in its input voltage.
