Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix NOPB indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the package type matches the required 10-VSSOP footprint for PCB integration. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with official TI documentation to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8V output is required from a variable input source. Consider the 90mA current limit for load requirements. Evaluate the 1000 kHz switching frequency for EMI constraints. The VSSOP package suits applications with limited board space. Verify compatibility with the system's thermal management capabilities within the specified temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the family of switched capacitor converters designed for low-power applications. It replaces discrete solutions by integrating the switching elements and control logic into a single IC. The NOPB suffix denotes a lead-free and RoHS-compliant variant, aligning with modern environmental regulations for electronic manufacturing.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible alternatives with similar electrical characteristics if sourcing is limited. Ensure any substitute maintains the 1.8V output and 90mA current capacity. Verify package dimensions match the existing footprint to avoid redesign.
