PQ3RD083J00H

The PQ3RD083J00H is a type of linear regulator commonly used in numerous types of electronics and machines. Its application field includes automotive, audio, industrial, instrumentation, peripherals, and telecommunications systems. This part features a high-output voltage accuracy, fast response time, and low quiescent current.

Linear voltage regulators are designed to maintain a steady voltage output, even if the input voltage varies. The output voltage is determined by resistors or potentiometers connected on the feedback pins. This regulator requires a few external components, such as two capacitors for stability and noise suppression. The series pass element of this regulator is a N-Channel enhancement mode MOSFET. It offers high switching speed and low gate-source threshold voltage.

The working principle of the PQ3RD083J00H regulator involves controlling a N-MOSFET’s conductivity based on an internal error amplifier. Creating a feedback loop in the control system, it compares the regulated output voltage with a precision voltage reference, adjusts the reference voltage level until the error signal is eliminated. In other words, the output voltage is equal to the reference voltage. When the output voltage falls below the voltage reference, the regulator is triggered, and a MOSFET is turned on and current is transferred to the output.

In summary, PQ3RD083J00H is a high-voltage linear regulator designed for automotive, audio, industrial and other application fields. It is designed to maintain a steady voltage output regardless of input voltage changes and features a powerful, fast response time and low quiescent current. With few external components and a simple feedback loop, this regulator provides accurate voltage output with minimal design requirements.
