Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments on official datasheets. Confirm the suffix /NOPB indicates lead-free compliance. Ensure the MM package code corresponds to the MSOP-10 footprint. Cross-reference the specific 2.0 V output variant against general family listings to avoid ordering incorrect voltage options.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.0 V rail is required from a 2.6 V to 5.5 V source. The 120 mA current limit suits low-power applications. The MSOP-10 package is appropriate for space-constrained designs. Consider the 500 kHz switching frequency for passive component sizing. Verify thermal performance within the specified operating temperature range.
