Working Principle

The PQ5EV5J0000H voltage regulator consists of a series of transistors, resistors, and diodes. The transistors form the core of the regulator, amplifying the input voltage and providing a constant output voltage. The resistors and diodes protect the transistors from over-voltages, preventing transistor failure. To provide a stable output voltage, the regulator uses two feed-back loops. The first loop, the error amplifier, reads the output voltage and modifies the current passing through the transistors until the desired output voltage is attained. The second loop, the reference stability loop, maintains the output voltage by adjusting the operating temperature of the regulator by controlling a temperature-sensitive resistor.

The PQ5EV5J0000H is a reliable and efficient voltage regulator, capable of maintaining a consistent output voltage in a variety of operating conditions. It is available in 1.5V-6V configurations, making it versatile and ideal for a variety of applications.
