PQ1KA423MZPH

Voltage regulators are an essential component of electrical systems in a multitude of consumer and industrial products. These components ensure that the correct voltage level is maintained in a circuit, even if system load or temperatures vary. The PQ1KA423MZPH is a linear voltage regulator offered by Panasonic that eliminates the need for complicated external components and maximizes system efficiency. This article will discuss the application field, features, and working principle of this valuable component.

Application Field

The PQ1KA423MZPH can be utilized in a wide variety of systems that require precise voltage regulation. Common uses include consumer electronics with AC/DC, DC/DC and DC/AC systems, industrial controls, motor controls, servers and storage, and telecommunications. The component is also suitable for high-noise and high vibration environments. All of these applications can benefit from the component’s low noise output and ultra-low drop-out voltage.

Features

The PQ1KA423MZPH is a feature-rich component that provides reliable voltage regulation in a cost-effective package. It is made of die-cast aluminum, which ensures a long-term lifespan, and offers ±2.0% DC output accuracy. The component can handle up to 40 kHz of maximum frequency, with an operating temperature range of -40 to +125°C. It is also RoHS compliant and offers protection from reverse-polarity damage.

Working Principle

The PQ1KA423MZPH utilizes a linear-control topology to provide precise voltage regulation. This component will take any incoming power, regulate it, and output it to the desired voltage. This is done through the use of an internal transistor, which is controlled by the component’s voltage reference. This reference voltage is generated from the resistor divider network, which divides the output voltage.

When the voltage in the component’s output exceeds its reference voltage, the transistor will turn on, allowing current to flow through it. This reduces the amount of power being output to the system. If the component’s output voltage is lower than the reference voltage, the transistor will turn off, and the system will receive a higher voltage.

The combination of these two processes allow the PQ1KA423MZPH to provide accurate voltage regulation to the circuit. This ensures that the circuit is operating optimally and that the system is protected from voltage spikes and drops.

Conclusion

The PQ1KA423MZPH from Panasonic is a versatile, feature-rich linear voltage regulator. This component is well-suited for a variety of applications, including consumer electronics, industrial controls, motor controls, and more. It is capable of withstanding extreme temperatures and providing accurate voltage regulation through its linear-control topology. With its low noise output, low drop-out voltage, and RoHS compliance, the PQ1KA423MZPH is a valuable component for any electrical system.
