Torex Semiconductor, Ltd. Voltage Regulators - Linear XC6503D191GR-G

The XC6503D191GR-G is a linear voltage regulator from Quarktwin Technology Ltd. designed to deliver a maximum output current of 500mA. It operates within an input voltage range of 1.7V to 6.0V and provides fixed output voltages from 1.2V to 5.0V in 0.05V increments. This device features internal phase compensation, allowing it to function without an external load capacitor, which can save board space in designs. The regulator includes protection features such as a current limit fold-back circuit and thermal shutdown to prevent damage under fault conditions. It has a typical quiescent current of 15OºA and a low standby current of 0.1OºA, making it suitable for low-power applications. The XC6503D191GR-G is available in a compact USP-4 package and is compliant with EU RoHS standards. Typical applications include smartphones, portable game consoles, and various wireless modules.
