What is the application of 7805 IC?
7805 Voltage regulator also finds usage in building circuits for inductance meter, phone charger, portable CD player, infrared remote control extension and UPS power supply circuits. More detailed information about the 7805 voltage regulator IC can be found in the datasheet.
What is the output voltage of IC 7912?
-12V
The LM7912 is a -12V Voltage regulator IC. Meaning it will provide a constant output voltage of -12V when the input voltage is between -14.5V to -27V. A very basic Voltage regulator circuit is shown below.
What is role of 7812 regulator in circuit?
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.
What are switching regulators used for?
Basic role A switching regulator can convert input direct current (DC) voltage to the desired direct current (DC) voltage. In an electronic or other device, a switching regulator takes the role of converting the voltage from a battery or other power source to the voltages required by subsequent systems.
What is a 79xx series regulator?
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. The ICs have inner current limiting protection and thermal shut down protection to shield the ICs from overload conditions.
What are the function of IC 7805 and IC 7905?
Being a linear regulator 7805 and 7905 drops necessary input voltage to derive +5V and -5V respectively in its output. A decoupling capacitor C3 is used to provide uninterrupted output just in case if there is any drop in output voltage of 7805 and 7905 in case of power failure.
What is the output voltage of 7905 IC?
-5V
In our case the 7905 IC is an negative 5V regulator, meaning it provides -5V as output. The name 7905 signifies two meaning, “79” means that it is a negative voltage regulator and “05” means that it provides 5V as output.
What is the expected output voltage of an LM7812 IC?
Product Type: Linear Voltage Regulators. Number of Outputs: 1 Output. Output Voltage: 12V. Output Current: 1.5A.
What does 7912 mean in ICS?
So “7912” means that this IC will regulate a negative 12V for your projects. You can also check on 78 series for positive voltage regulators. When you are designing an analog circuit, the circuit might need negative voltage either as a power source or as a reference voltage.
How does the lm7912 work?
The LM7912 is a -12V Voltage regulator IC. Meaning it will provide a constant output voltage of -12V when the input voltage is between -14.5V to -27V. A very basic Voltage regulator circuit is shown below. I have used a Battery to power the IC, but you can use any power source but notice that the supply voltage should be negative.
