Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CER' against the official Torex datasheet to confirm the exact output voltage, package type, and tape/reel specifications. Ensure compatibility with the target PCB footprint for the SOT-25-5 package. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and current availability status before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.8 V output is required from a single-cell lithium-ion battery or similar low-voltage source. The 0.8 A output current capability suits moderate load applications. Consider the available switching frequencies to balance between component size and electromagnetic interference requirements. Verify that the input voltage range covers the minimum operating voltage of the system.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9142 series of 0.8 A synchronous step-up DC/DC converters from Torex Semiconductor.
