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

Verify the manufacturer origin as Fairchild Semiconductor or its successor entities like onsemi due to corporate acquisitions. Confirm the specific suffix 'M531X' corresponds to the SOT-23-5 package and RoHS compliance status. Ensure the part number matches the exact 3.1V fixed output variant rather than adjustable versions within the same family.

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

Select this component when a stable 3.1V rail is required from a higher input source. It is appropriate for low-power circuits drawing up to 100mA. Consider the thermal performance in the small SOT-23-5 package if ambient temperatures are high. Verify that the input voltage does not exceed the maximum rating of 13V.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the ILC708x series of low-dropout regulators designed for efficiency in portable equipment. Fairchild Semiconductor developed this line to replace older LDO technologies with improved noise and dropout characteristics. The series includes various fixed voltage options and adjustable variants.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for equivalents such as the ILC7081AIM531X from onsemi following the acquisition. Other 3.1V fixed LDOs in SOT-23-5 packages may serve as substitutes if pinouts and electrical parameters align.
