What is the use of IC 7805?
A voltage regulator IC maintains the output voltage at a constant value. 7805 Voltage Regulator, a member of 78xx series of fixed linear voltage regulators used to maintain such fluctuations, is a popular voltage regulator integrated circuit (IC). The xx in 78xx indicates the output voltage it provides.
What is the use of IC LM317?
The LM317 serves a wide variety of applications including local, on card regulation. This device can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM317 can be used as a precision current regulator.
What is the function of IC 7812?
The ic 7812 is a positive voltage regulator which means that it generates the positive voltage with respect to the common ground. In case if both the positive and negative voltage supply is needed in the same circuit. The voltage regulator ic 7812 is combined with its corresponding 79XX family IC that is 7912 IC.
Which IC is used for power supply?
Power supply ICs are roughly divided into two types: linear regulators and switching regulators. In the case of a linear regulator, the only output format is buck (step-down) operation that generates a lower voltage than the input voltage.
What is the difference between LM317 and LM337?
LM317 is a positive voltage regulator and LM337 is the negative compliment voltage regulator IC of LM317. The LM317 IC is a 3-terminal voltage regulator that is designed to supply in excess of 1.5 Amps of a DC output voltage range of (1.2-30) Volts.
What is the output of the IC 7812?
The series 79XX regulators are the three-terminal IC regulators that provide a fixed negative output voltage….Detailed Solution.
| IC Part | Output Voltage (V) | Minimum Vi (V) |
|---|---|---|
| 7808 | +8 | +10.5 |
| 7809 | +9 | +11.5 |
| 7812 | +12 | +14.6 |
What is the output voltage of 7812?
The 7812 is a fixed voltage linear regulator that can output 12V at up to 1A current with an input voltage range of 14 – 35V.
What kind of circuit is an IC 7808?
About 7808 Voltage regulator. 7808 Voltage regulator is a type of self-contained fixed linear voltage regulator integrated circuit. The IC belongs to 78xx voltage regulator family which is commonly used as the regulated power supply in electronic circuits.
Who is the manufacturer of the 7805 IC?
Currently, the 7805 Voltage Regulator IC is manufactured by Texas Instruments, ON Semiconductor, STMicroelectronics, Diodes incorporated, Infineon Technologies, etc. They are available in several IC Packages like TO-220, SOT-223, TO-263 and TO-3.
What should the current be for a 7808 voltage regulator?
About 7808 Voltage regulator. The 7808 Voltage regulators do operate at their optimal capability if the input voltage is at least 2.5 volt greater than the output voltage and the current is 1 or 1.5 Amperes more. Though the voltage and current different is different for other IC Packages.
Why does the IC 7808 have a heat sink?
The 7808 ic has built-in protection from the high current. There is a heat-sink with the common ground connected with which is helpful in order to prevent our regulator ic from overheating and short-circuits making it uncompromising in the most application.
