Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging rather than tube. Confirm the manufacturer is Texas Instruments, as previous National Semiconductor branding may appear in legacy listings. Ensure RoHS compliance documentation matches the NOPB designation. Cross-reference the datasheet revision date to confirm technical specifications align with current manufacturing standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 12V output is required from a higher voltage rail up to 60V. The TO-263 package suits applications needing moderate heat dissipation without through-hole constraints. Compare against adjustable variants if flexible output voltages are needed later. Consider the 52kHz frequency impact on inductor size versus higher frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context
