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

Verify the specific suffix 'Y' corresponds to the SOT-89-3 package and '-13' indicates tape and reel packaging. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements during storage and handling. Ensure the application circuit includes recommended ceramic capacitors as specified in the datasheet to maintain stability.

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

Select this component when a fixed 5.0V rail is required with high input voltage tolerance up to 30V. It is suitable for designs prioritizing low standby power due to its microampere-level ground current. Verify that the expected load current does not exceed 150mA and that the PCB layout accommodates the thermal dissipation needs of the SOT-89 package under maximum load conditions.
