It is an adjustable, cost effective choice with high PSRR and excellent line regulation. The device is available in a 7- pin SOT23 package and is ideally suited for use in a variety of consumer, industrial and professional applications.

Application Field

The AP2202K-2.5TRE1 is well-suited for use in a wide range of consumer, industrial and professional applications. The device provides an adjustable output voltage with low dropout and is capable of working with input voltages of up to 10V. It is also compatible with low quiescent current power sources such as Li-ion/Lithium-polymer batteries and is capable of delivering up to 1.5A of output current. The device is ideal for applications such as:

• Digital still cameras, camcorders, audio equipment and portable medical instruments.
• Consumer and commercial electronics including LCD TVs, DVD players, disk drives, gaming consoles, remote controls and mobile phone accessories.
• Industrial and communications systems including frequency synthesizers, digital set-top boxes, Wi-Fi access points and broadcast equipment.

Working Principle

The AP2202K-2.5TRE1 is a linear voltage regulator that works by controlling the current through an adjustable output impedance. It uses a two-terminal source-impedance configuration to regulate the output voltage to a voltage that is lower than the input voltage. The output voltage is adjusted by changing the impedance of the source-impedance configuration. This is achieved by changing the values of the series resistors connected to the output voltage. By controlling the impedance of the series resistors, the output voltage of the regulator can be adjusted up or down. The device also has a feedback loop that compares the output voltage with a reference voltage. If the output voltage comes within a certain range of the reference voltage, the device will adjust the current through the output by varying the impedance of the series resistors. This ensures that the output voltage remains within the set range. In addition, the AP2202K-2.5TRE1 has several other features, such as over-current protection, thermal protection and reverse voltage protection, which help to enhance its safety and reliability.

Conclusion

The AP2202K-2.5TRE1 is a linear voltage regulator produced by Diodes Incorporated that can handle up to 1.5A of output current. It is suitable for a broad range of consumer, industrial and professional applications and has features such as over-current protection, thermal protection and reverse voltage protection. The device works by controlling the current through an adjustable output impedance, and its output voltage can be adjusted by changing the values of the series resistors.
