What is a Voltage Regulator?
A voltage regulator is a device that maintains a constant output voltage level. It’s like the superhero of your electronic devices, ensuring they get the right amount of power and don’t go boom!
Voltage Regulator Calculation Formula
Here’s the serious stuff. The voltage regulator calculation formula is pretty straightforward. It’s given by:
Output Voltage = Input Voltage * (Duty Cycle / Period)
Different Types of Voltage Regulators
| Category | Type | Voltage Range (V) |
|---|---|---|
| Linear | Series | 1.2 – 37 |
| Linear | Shunt | 2.5 – 36 |
| Switching | Step-down (Buck) | 1.23 – 35 |
| Switching | Step-up (Boost) | 3 – 35 |
Voltage Regulator Calculation Examples
| Example | Input Voltage (V) | Duty Cycle (%) | Period (ms) | Output Voltage (V) | Calculation |
