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

Verify the specific suffix '7B' corresponds to the X2-DFN1010-4 package type and tape & reel packing configuration as defined in the manufacturer's ordering guide. Confirm that the 'D' designation indicates the inclusion of the auto-discharge feature on the output pin, which distinguishes it from non-discharge variants.

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

Select this component when a compact footprint is required alongside high PSRR performance. Ensure the application load does not exceed the guaranteed 300mA output current limit. Verify that the input voltage remains within the specified 1.7V to 5.25V range to maintain proper regulation and stability under all operating conditions.
