Introduction
XC6504A281MR-G is a voltage regulator designed and produced by ZYGA Technology. It is an intelligent, highly programmable and configurable single-output voltage regulator. It is cost efficient and highly reliable, with a wide input voltage range of 8-40V and a good output voltage regulation. This voltage regulator can be used in a wide range of applications, including audio and video playback, communications, automotive electronics, digital home applications, power supplies, and medical equipment.
Application Field
XC6504A281MR-G is a power management IC (PMIC) voltage regulator an integrated linear voltage regulator. It can be used for inputvoltage regulation, output voltage regulation, and monitoring various powersupply voltages. The linear regulator requires an external resistor for setting the output voltage, and provides a predictable output voltage accuracy that is ideal for meeting tight power supply accuracy requirements. The XC6504A281MR-G has typical responses to load and input impedance, stable output noise level over temperature and high PSRR performance. It also offers a wide package selection and is ideal for battery operated applications such as PC’s, PDAs, cellular phones, portable audio/video products and other electronic devices. Working Principle
The XC6504A281MR-G uses a linear regulator to convert its input voltage to an output voltage that is constant or variable. The output voltage is programmed using different combinations of resistors. The basic function of the voltage regulator is to provide a stable output voltage when the input voltage varies. The regulator consists of an error amplifier, a pass element, a reference voltage source, a control feedback network, and a power control circuit. The error amplifier monitors the output voltage and compares it to the reference voltage. If the output voltage is too high, the error amplifier decreases the output voltage. Otherwise, it increases it. The pass element provides the regulation, and the power control circuit provides the current to the load.The XC6504A281MR-G has overrun protection and short-circuit protection. The overrun protection protects the circuit by placing a limit to the output voltage, ensuring it does not rise above a certain value. The short-circuit protection protects the output from overloading. It automatically shuts down the output when the load current reaches the overcurrent limit.Conclusion
The XC6504A281MR-G is an integrated linear voltage regulator designed and produced by ZYGA Technology. Its wide input voltage range, good output voltage regulation, overrun protection, and short-circuit protection makes it perfect for a variety of applications. It is suitable for input voltage regulation, output voltage regulation, and monitoring various power supply voltages. Its erratic noise level and high PSRR performance makes it ideal for battery operated applications such as PC’s, PDAs, cellular phones and portable audio-video devices.
