Linear voltage regulators are powered electronic components that regulate the output voltage to a preset level, despite fluctuations in the input voltage. It s essential to use a linear regulator when there is either a large voltage drop or because the load requires a very precise output voltage. The PQ12RA1 is a linear voltage regulator produced by Power Integration. It has a wide range of applications, from providing precise voltages for hospital X-ray machines to powering computer components. This article will discuss the application fields and working principles of the PQ12RA1.

Working Principle of the PQ12RA1

The PQ12RA1 is a linear voltage regulator that uses MOSFET technology. It works by using power MOSFETs to regulate the output voltage by controlling the duty cycle of the switches. When the input voltage is lower than the preset output voltage, the power MOSFET turns on, allowing current to flow from input to output. When the input voltage is higher than the preset output voltage, the power MOSFET turns off, limiting the current that can flow through the component. This maintains the output voltage at the desired level despite fluctuations in the input voltage.

Conclusion
