AP131-20WL-7 Application Field and Working Principle

AP131-20WL-7 is a voltage regulator from A&P Technologies which offers high performance, cost-effective solutions for low-power electronic systems. This low dropout (LDO) regulator provides output voltages from 1.5V up to 5.0V with only a few external components. This product is designed for Battery-Powered and Microprocessor Interfacing Applications.

AP131-20WL-7 is an adjustable linear regulator that can deliver up to 1.2A of current to its intended application. This linear regulator is a voltage regulator which holds a fixed output voltage with little fluctuation beyond normal current fluctuations. The output voltage is set through an external resistive network allowing the parts to be used with output voltage settings ranging from 1.5V to 5.0V. The device also has additional features to ensure a safe operating condition during fault conditions, low supply conditions and over temperature conditions. The power-saving operation of the device further reduces current consumption during idle conditions such as standby or low power operation.

The device has an on-board voltage reference (XREF) which provides an adjustable output voltage. This on-board voltage reference can be tuned from 1.5V to 5.0V by adjusting the external resistor. An enable pin (EN) allows the user to manually turn off and on the output of the device when needed. The AP131-20WL-7 also features a high ripple rejection, low dropout voltage, and low quiescent current. The AP131-20WL-7 is available in an industry standard 8-pin DIP, 8-pin SOIC, 14-pin DIP, 14-pin SOIC and 8-pin DFN packages.

The AP131-20WL-7 is suitable for use in a variety of applications such as mobile phones, digital cameras, audio/video equipment, handheld devices, monitors and other products requiring low power consumption and high accuracy voltage regulation. With its high accuracy, low-dropout voltage, low quiescent current and thermal shutdown protection, the AP131-20WL-7 is the perfect solution for efficient power management in portable and low-power applications. Additionally, its Suitable ESD protection allows safe operation in sensitive environments.

In summary, the AP131-20WL-7 is an adjustable linear voltage regulator with excellent performance and low power consumption. Its on-board voltage reference and enable pin provide precise, adjustable output voltages from 1.5V to 5.0V with high accuracy, low-dropout voltage, low quiescent current, and thermal shutdown protection. With its industry standard packages, the AP131-20WL-7 is ideal for a variety of low-power applications requiring highly accurate, efficient regulation of power.
