AP7343-185FS4-7B is an adjustable regulator with a low output voltage range of 0.88V to 1.8V and a dropout voltage range of 0.2V. It is a highly integrated and cost-effective PMIC solution for system applications, including portable electronics and automation systems.

Introduction

The AP7343-185FS4-7B is a linear voltage regulator with low noise and low power consumption. It provides adjustable output voltage control and is ideal for applications such as TV/monitor supplies, notebook and tablet PC supplies, office automation supplies, POS equipment, and cellular device supplies. The linear regulator features an internal power MIP (Metal Insulator Power on) device, which offers the lowest dropout voltage available in linear regulators of this type. This low dropout voltage allows the AP7343-185FS4-7B to operate at the maximum input voltage of 1.8V.

Application Field

The AP7343-185FS4-7B is well suited for applications where both high efficiency and low cost are desired. It is ideal for battery-powered equipment with a single cell Li-Ion battery, such as tablets, notebooks, and cell phones, as well as other applications requiring a low output voltage and low dropout voltage. Additionally, the AP7343-185FS4-7B can be used for voltage regulation in supply circuits for FPGA and MCUs in entry-level micro products such as hand-held devices.Additionally, this linear regulator provides the following advantages:- Low power consumption- Low dropout voltage- Fast response time- High efficiency- Very good transient response

Working Principle

The AP7343-185FS4-7B is a low dropout linear voltage regulator. It operates in three modes: Regulation, Shutdown, and Power-On. In regulation mode, the regulator is in control of the output voltage and maintains it at a steady level in the presence of the load. During power-on, the regulator provides a constant regulated voltage to the load, while the device is in its startup phase, until the output voltage reaches the targeted level. In shutdown mode, the regulator stops supplying the output voltage and the sudden stoppage of service avoids damage caused by large inrush currents.Specifically, the AP7343-185FS4-7B works by utilizing an internal MIP to reduce the dropout voltage, or the difference between the regulator\'s input and output voltages. This MIP, along with other components, acts as a voltage reference to the output transistor, allowing it to accurately control the voltage. This allows the regulator to maintain its target output voltage, even at very low input voltages.

Conclusion

The AP7343-185FS4-7B is an adjustable linear regulator that is ideal for cost-effective applications that require low power and high efficiency. It features an internal MIP device that provides the lowest dropout voltage available on the market, allowing it to operate at very low input voltages and maintain a specified output voltage. This device is well suited for applications such as TV/monitor supplies, notebooks, tablets and cellular devices.
