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

Verify the specific suffix FDZW corresponds to the W-DFN2020-6 wettable flanks package type required for your PCB layout. Confirm that the -7 suffix indicates tape and reel packaging with a standard quantity of 3000 units per reel. Ensure the ordering code matches the exact 1.2V fixed output version needed for the design specifications.

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

Select this part for noise-sensitive automotive applications requiring high PSRR and low quiescent current. The W-DFN2020-6 package offers a small footprint suitable for dense layouts. Verify that the input voltage remains within the 1.7V to 5.5V range and that the load does not exceed the 500mA guarantee. Consider the thermal resistance characteristics of the exposed pad for heat dissipation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the function of the EN pin?

The EN pin enables or disables the regulator. Driving it high turns the regulator on, while pulling it low activates shutdown mode with an internal active discharge feature.
