XC6503D331MR-G Description

Short technical summary and product information.

The XC6503D331MR-G from Torex Semiconductor is a linear voltage regulator designed for efficient power management. It provides a stable 3.3V output voltage with a maximum input voltage of 6V. The device operates with a very low quiescent current of 30µA, making it suitable for battery-powered applications where low power consumption is critical.

 

Key electrical characteristics include a voltage dropout of 0.23V at 300mA and a Power Supply Rejection Ratio (PSRR) of 55dB at 1kHz, ensuring clean power delivery. Protection features such as over-current and over-temperature shutdown are integrated for enhanced reliability.

 

This regulator is available in a SOT-25 package, designed for surface mounting. Its operating temperature range is -40°C to 85°C (TA), allowing for use in various environmental conditions. The XC6503D331MR-G is ideal for new designs requiring reliable and efficient power regulation in a small form factor.
