Torex Semiconductor, Ltd. Voltage Regulators - Linear XC6220A391ER-G

The XC6220A391ER-G is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a stable output voltage with a maximum output current of 1A. It features a low dropout voltage, making it suitable for battery-powered applications, and incorporates a Green Operation function that allows automatic switching between high-speed and power-saving modes to enhance battery life. The output voltage is adjustable in increments of 0.05V within a range of 0.8V to 5.0V, achieved through laser trimming technology. This regulator includes built-in protection features such as overcurrent protection and thermal shutdown, which activate under specific conditions to prevent damage. An inrush current prevention circuit minimizes voltage fluctuations during startup, and the CE function allows for reduced power consumption by enabling a standby mode. The XC6220A391ER-G is compatible with low ESR ceramic capacitors for output stabilization and is available in various package types, including USP-6C, SOT-25, and SOT-89-5, all of which are EU RoHS compliant. Applications for this voltage regulator include optical and magnetic disk drives, digital cameras, camcorders, and digital audio equipment, making it a versatile choice for various electronic projects.
