Linear voltage regulators are intended to serve as a low-dropout (LDO) regulator to supply a stable regulated output voltage despite changes in the input voltage and load. The XC6501A28A7R-G is a low-noise, low-dropout linear regulator capable of providing a regulated 3.3V output from an input voltage of 2.5V to 6.0V. It also features a built-in sense resistor to achieve excellent load regulation and has low output voltage noise due to its low quiescent current. This makes it well suited for applications such as providing a regulated 2.5V output voltage for main system operation, or providing a regulated 3.3V or 5V output for portable devices.

With its low drop-out voltage and high power efficiency, the XC6501A28A7R-G is suitable for battery-powered applications, such as PDAs, cellular phones, and portable media players. It also includes other features, like an engine test mode capability, which helps reduce development time during the testing and evaluation of a system. The XC6501A28A7R-G also boasts a thermal shutdown function, built-in over-current limiting, and a low drop-out voltage of up to 250mV.

The XC6501A28A7R-G operates by taking the input voltage and dropping it a certain amount to attain the desired output voltage. The difference between the input and output voltage is the drop-out voltage and it is determined by the load current draw and the output voltage. The XC6501A28A7R-G keeps the output voltage constant by continually adjusting the input voltage based on the load current. To do this, the device utilizes a negative feedback loop in which an error signal is generated, taking into account the input voltage, the output voltage and the load current. The error signal is used to control the internal on-board circuitry, which adjusts the drop-out voltage as needed.

The XC6501A28A7R-G utilizes an advanced circuit design and numerous integrated features. Like other linear regulators, the XC6501A28A7R-G features low drop-out voltage and high power efficiency. It also offers protection against overloaded conditions and short circuits, as well as thermal shutdown protection. The XC6501A28A7R-G also boasts a low output noise level, which makes it suitable for noise-sensitive applications. By utilizing an onboard sense resistor, the XC6501A28A7R-G can achieve excellent load regulation.

The XC6501A28A7R-G is a great option for a wide range of applications, such as providing a regulated 3.3V output voltage in consumer electronics and portable media players, providing a regulated 5V output in mobile phone chargers, or providing a regulated 2.5V output in laptop, tablet, and cell phone systems. Its combination of excellent load regulation, low drop-out voltage, and low noise output makes it perfect for these applications. The XC6501A28A7R-G is also available in a wide range of package options and other configurations, allowing it to easily be integrated into any system.
