Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the Not Recommended for New Designs (NRND) status before finalizing procurement plans. Confirm that existing inventory meets long-term production requirements as new design adoption is discouraged. Ensure compatibility with the specified QFN-14 footprint and thermal management needs during integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 20 V and high output current capability are required. Consider the NRND status carefully for new projects. Evaluate the trade-off between the 1 mA quiescent current and the need for high efficiency under heavy loads compared to newer alternatives in the MPS portfolio.
