Additional Details

The XC6201P172MR provides a fixed output voltage of 1.7V, as indicated by the '17' in the part number. The 'MR' suffix typically refers to the package type, which is likely a small SOT-23 or similar package. It operates over a wide temperature range, typically from -40°C to +85°C. The low dropout voltage characteristic is critical for maintaining a stable output voltage as the battery voltage decreases. The integrated overcurrent protection and thermal shutdown features protect the regulator and the load from damage, ensuring reliable operation even under fault conditions. The low quiescent current minimizes power consumption when the regulator is not actively supplying current to the load, making it ideal for battery-powered applications. Its small size and integrated features make it well-suited for a variety of portable and space-constrained applications requiring stable and efficient voltage regulation. The 1.7V output voltage is suitable for powering a variety of low-voltage microcontrollers and other components.
