PQ3DZ13 is a linear voltage regulator which is powered by a positive DC voltage, usually at the range of 0-5.5V, and it produces a constant output voltage at the range of 0-5V. This device is designed with SOIC-8 package, and it is among the family of Energizer, which is renowned for its long-lasting universal energy sources like batteries and solar energy. This voltage regulator is capable of providing current up to 250mA, and its low supply current makes it an ideal option for applications which require efficient power consumption. The PQ3DZ13 is widely used in various industrial, medical and commercial applications.This voltage regulator is classified as linear regulator because it employs a linear control element, transistor, to regulate the output voltage. The circuit takes the input voltage and subtracts a voltage drop which is developed by the control element.The output voltage is tension applied across a series consisting of a preset resistor, a transistor and a zener diode. This creates a voltage difference between the input voltage and the output voltage. In the PQ3DZ13 linear regulator, since there is no feedback control employed, its output voltage is not highly stable. In addition, because the output voltage is stored on the control element, it is not possible to achieve a voltage polarity reversal.Due to its compact size and cost-effective nature, the PQ3DZ13 proximity switch is widely used in various industrial, medical and commercial applications. In industrial applications, the linear regulator can be used to regulate the power in process control and automation. Since it provides accurate and stable power source, it is widely used in medical instruments and medical devices. In commercial applications, the linear regulator is used for various electronic devices such as telephone systems, security systems, automated teller machines and IT systems.In a PQ3DZ13 linear regulator, the working principle is quite simple. First, the regulator takes the input voltage and subtracts a voltage drop with the control element. As the voltage drop decreases, the output voltage will also decrease accordingly. In order to maintain an appropriate output voltage, the control element needs to be chosen in such a way that its maximum capability matches the maximum power needs. Finally, the output voltage is obtained by the series connection of a resistor, a transistor, and a zener diode. By adjusting the resistors to the various values, the output voltage can be adjusted to the desired level.In conclusion, the PQ3DZ13 linear regulator is a key component of a variety of industrial, medical and commercial applications. Its compact size and cost-effective nature make it an ideal choice for various purposes. Its linear working principle is also relatively simple and straight forward. Moreover, it can provide a stable and consistent output voltage without the need for feedback control. Hence, for various applications, the PQ3DZ13 linear regulator would be an ideal solution to provide a reliable power source.
