Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix FDZW corresponds to the W-DFN2020-6 (SWP) package type required for your design. Confirm that the -7 suffix indicates tape and reel packaging containing 3000 units per reel. Ensure the component meets RoHS 3 compliance standards if applicable to your manufacturing region. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity before procurement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for noise-sensitive automotive environments requiring high PSRR and low output noise. The 2.8V fixed output suits systems needing precise voltage regulation without external resistors. Verify input voltage stability remains within the 1.7V to 5.5V range under all operating conditions. Consider the thermal resistance characteristics of the W-DFN2020-6 package for heat dissipation planning.
