Additional Details

The XC6201P342MR is a fixed output voltage LDO regulator with a 3.4V output, as indicated by the '34' in the part number. The 'MR' suffix generally designates the package type, often a small SOT-25 or similar surface-mount package. It is designed to operate over a wide temperature range. The low dropout voltage characteristic is particularly important in battery-powered applications, as it allows the regulator to maintain a stable 3.4V output voltage even as the battery voltage decreases. The integrated overcurrent protection, thermal shutdown, and short-circuit protection features enhance the reliability and robustness of the system. The low quiescent current minimizes power consumption when the regulator is not actively supplying current to the load, further contributing to extended battery life. The compact package size and integrated protection features make it well-suited for a wide range of portable and space-constrained applications requiring a stable and efficient 3.4V supply. Detailed specifications, including the input voltage range, output current capability, and thermal characteristics, can be found in the product datasheet.
