With the development of microelectronics technology, the power supply products become more and more high-tech and there are more and more products in the market. As a part of the field, PMIC (Power Management Integrated Circuit) is commonly used. Among them, linear voltage regulator is one of the most commonly used. In this article, the application field and working principle of the linear voltage regulator AP7343D-135W5-7 will be introduced.

Application Field

Linear voltage regulator is mainly used in fields with small power and low ripple, such as digital signal processor, programmable logic device, digital radio and other low-power digital systems. The AP7343D-135W5-7 linear voltage regulator is designed for mobile devices such as cellular phones and digital cameras to regulate and stabilize 3.4V output voltage for processor and other digital circuits. It meets the needs of high-speed circuits, low-power dissipation, high-input voltage, ultra-high short-circuit current, improved offset voltage, broad ripple rejection and hundreds of other requirements.

Working Principle

The working principle of the linear voltage regulator is to adjust the output voltage through a feedback circuit. The feedback circuit consists of three parts: an error amplifier, an error amplifier feedback resistor network and a series pass element. When it is working, the output voltage is compared with the output voltage reference. The error amplifier generates a current proportional to the voltage difference between the two. The error amplifier feedback resistor network changes the current into the output voltage. Finally, the output voltage is regulated by the pass element.

One of the features of the AP7343D-135W5-7 is that it can output up to 135W5mA of steady current over a wide temperature range. It adopts a high-efficiency buck topology circuit to avoid the power loss of the linear regulator. The integrated low-dropout voltage regulator can tolerate input voltage up to 6.5V. In addition, the AP7343D-135W5-7 has an adjustable output voltage range of 3.3V-3.4V. The minimum output voltage is 3.3V and the maximum output voltage is 3.4V, which can meet the power supply requirements of most electronic products.

Conclusion

The AP7343D-135W5-7 is a linear voltage regulator IC with a wide range of applications. Its working principle and features can meet the needs of most products, making it one of the most commonly used in the market. When selecting a linear voltage regulator, it is necessary to analyze the parameters of the product and select the most suitable one according to the actual situation.
