Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9265A381MR-G

The XC9265A381MR-G is an ultra-low power synchronous step-down DC/DC converter designed for high efficiency in battery-operated devices. It operates within an input voltage range of 2.0V to 6.0V and provides a fixed output voltage of 3.8V with an accuracy of ¬±2.0%. The device can deliver an output current of up to 200mA and features a low quiescent current of 0.50OºA at VOUT=1.8V, making it suitable for applications requiring extended battery life. This regulator employs pulse frequency modulation (PFM) control, which enhances efficiency during low load conditions. It includes built-in functions such as under-voltage lockout (UVLO) to protect against low input voltage conditions and a CL discharge feature that allows for rapid output voltage restoration during standby mode. The XC9265A381MR-G is compatible with ceramic capacitors, simplifying external component requirements to just an inductor and input/output capacitors. Operating over a temperature range of -40¬8C to 85¬8C, this product is suitable for various applications, including wearable devices, smart meters, Bluetooth units, and portable game consoles. The XC9265A381MR-G is packaged in a SOT-25 format and is compliant with EU RoHS standards, ensuring it meets environmental regulations.
