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

Verify that the specific part number matches the required fixed output voltage and pin configuration. Confirm the package type aligns with PCB layout requirements. Ensure the application environment stays within the specified operating temperature and voltage limits to maintain performance and reliability.

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

Select this component when a stable 2.6V supply is needed for portable electronics. Consider its low quiescent current for battery-powered applications. Verify that the external capacitor selection meets the stability requirements despite the wide ESR tolerance. Ensure adequate thermal management on the PCB if high power dissipation is expected.

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

This device belongs to the FAN2504/05 family of micropower low-dropout regulators. The FAN2504 series distinguishes itself by offering adjustable or bypassed outputs at Pin 4, unlike the FAN2505 which provides an error flag. This specific model represents the fixed 2.6V variant optimized for cost-effective performance in compact consumer devices.

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

The datasheet notes that the FAN2504/05 family is pin-compatible with many popular older BiCMOS designs. Designers replacing legacy components should verify that the new LDO's electrical characteristics meet the original circuit requirements without modification.
