Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments or National Semiconductor on the datasheet. Confirm the suffix indicates lead-free (Pb) compliance. Ensure the package type matches the required 14-pin HTSSOP footprint. Check for specific ordering codes such as NOPB if lead-free status is mandatory for the assembly process.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from a single-cell lithium-ion or similar low-voltage source. The choice depends on the need for integrated synchronous rectification to minimize external component count. Consider the thermal performance of the HTSSOP package relative to the expected load current and ambient conditions.
