Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DMR' corresponds to the SOT-25-5 package and reel packaging requirements. Confirm that the fixed 1.25V output aligns with system design needs, as adjustable variants exist within the series. Ensure compatibility with 3MHz switching frequency constraints in the target application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.25V output is required from a 2V to 6V input source. The 600mA current capacity suits moderate load applications. Consider the 3MHz switching frequency for balancing component size and efficiency. Verify thermal performance within the specified operating temperature range for the intended enclosure.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9235 series of synchronous-rectification type DC/DC converters. The series is designed to allow the use of ceramic capacitors, reducing external component count. The XC9235 variant specifically employs PWM control, distinguishing it from the automatic PWM/PFM switching modes found in the XC9236 and XC9237 series counterparts.
