What is voltage regulation using IC?
The function of a voltage regulator is to maintain a constant DC voltage at the output irrespective of voltage fluctuations at the input and (or) variations in the load current. Voltage regulators are also available in Integrated Circuits (IC) forms. These are called as voltage regulator ICs.
What is VCC and GND in IC?
VCC (Voltage Common Collector) is the power supply of a device . Ground is the the reference point against which the VCC is compared. It can be positive or negative compared to GND. When the VCC is at zero colts, it is called the ground.
How is the voltage of an IC regulator calculated?
The resistor R2 is adjusted to get the output voltage range between 1.2 volts to 57 volts. The output voltage that is required can be calculated using the equation: In this circuit, the value of Vref is the reference voltage between the adjustment terminals and the output taken as 1.25 Volt.
How to calculate voltage across a series circuit?
In a series circuit, the sum of all your answers must equal the total voltage. Add up every voltage you calculated and see if you get the voltage of the entire circuit. If you didn’t, go back and check for mistakes. In our example, 2.4 + 3.6 + 6.0 = 12 volts, the voltage across the whole circuit.
What is the voltage across a 1kΩ resistor?
In the circuit we have four 1kΩ resistors, the voltage across each resistor will be equal to Vcc/4. If the voltage across the total resistor is 12V then the voltage across each resistor is 12/4 =3V.
Which is the ideal voltage across a short circuit?
This is an ideal open circuit; the current is zero for any voltage across. Now, consider the I-V characteristic for an ideal resistor with a small resistance: As R → 0, the slope approaches infinity, i.e., the I-V characteristic becomes vertical through the origin. This is an ideal short circuit; the voltage is zero for any current through.
