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

Verify the specific suffix 'S' indicates the SOT-23-5L package variant and 'N180' confirms the 1.8 V fixed output. Confirm RoHS compliance and Pb-free status as stated in the ordering information. Ensure the version matches the required active discharge functionality associated with the 'A' option in the series.

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

Select this component when designing for applications requiring minimal noise injection into RF or analog signal paths. The SOT-23-5L package offers a balance between thermal dissipation and board space compared to smaller WLCSP options. Verify that the load current requirements do not exceed the 250 mA limit and that the input voltage remains within the specified 2.2 V to 5.5 V range.
