Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'E' indicates the correct output voltage tolerance and package variant against the official datasheet. Confirm the 'CER' designation matches the required 6-USPC package with exposed pad. Ensure compatibility with your PCB footprint and thermal requirements before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 4.0V output is required from low-voltage sources up to 6V. The 800mA current capability suits moderate load applications. Consider the 1.2MHz switching frequency for smaller passive components compared to lower-frequency alternatives. Verify that the load disconnection feature meets your standby power constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9141 series of 0.8A step-up DC/DC converters. The series is characterized by its integrated load switch and synchronous topology. Other variants in the family offer different fixed output voltages and package options, such as SOT-25-5 or SC-74A, while maintaining similar electrical performance characteristics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes within the same series include XC9141E35CER-G (3.5V output) and XC9141E45CER-G (4.5V output) if voltage adjustment is permissible. Cross-brand replacements require matching the 0.8A current rating, 1.2MHz frequency, and synchronous boost topology.
