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

Verify the specific suffix W5 confirms the SOT25 package type and the '12' indicates the 1.2V fixed output. Ensure the absence of the 'D' suffix confirms the non-discharge variant. Confirm RoHS compliance and lead-free status as specified in the ordering information section of the datasheet.

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

Select this component when a fixed 1.2V rail is required with minimal static power consumption. The SOT25 package offers a compact footprint suitable for space-constrained designs. Verify that the input voltage remains within the 2.0V to 5.5V range and that the load current does not exceed 150mA for optimal performance.
