The XC6504A131NR-G is a low drop-out (LDO) voltage regulator manufactured by Torex Semiconductor. It is capable of providing output voltages of 3.3V, 5V, and 8V and offers an ultra-low quiescent current of 0.6uA. It is designed for easy integration in a wide range of applications, providing great stability and reliability due to its low current consumption. It features a high ESR, above-normal thermal resistance, low output noise, and low reverse current. This makes it suitable for applications requiring ultra-low power consumption, such as battery-powered devices. The XC6504A131NR-G is packaged in a small SOT-25 package, enabling it to fit into small, highly portable electronics.
