Power Management - Specialized Procurement Notes

Verify the specific suffix 'T' if tape-and-reel packaging is required, as the base part number may denote tube packaging. Confirm current availability status, as this component may be subject to limited supply or end-of-life restrictions. Ensure the 28-SSOP package dimensions align with the target PCB layout constraints before finalizing procurement decisions.

Power Management - Specialized Selection Notes

Select this component for designs utilizing a single-cell battery source that requires regulated output voltage for two-way pager functionality. The integrated step-up converter simplifies the bill of materials by combining power management and regulation into a single chip. Consider the thermal performance and physical size of the 28-SSOP package when evaluating space-constrained mobile device enclosures.
