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

Verify component authenticity through authorized distribution channels due to obsolete status. Confirm package integrity upon receipt as the SOT-23-5 form factor is sensitive to moisture and physical damage. Cross-reference datasheet revisions to ensure compatibility with existing design specifications. Validate that the specific suffix matches the required electrical characteristics for the target application.

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

Select this component when a stable 2.5 V rail is required for low-power CMOS logic or RF sections in portable systems. The 150 mA current capability supports moderate loads while maintaining low quiescent current. Ensure the input voltage remains within the 6.5 V maximum limit. Consider the SOT-23-5 footprint constraints during PCB layout. Verify that the thermal performance meets the ambient operating requirements without additional heatsinking.

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

This part belongs to the FAN2513 family of low-dropout regulators designed for cost-effective performance in portable electronics. It utilizes CMOS technology to achieve low power consumption compared to bipolar alternatives. The series is optimized for applications requiring fast start-up times and minimal external components. It serves as a legacy solution for older mobile phone and computing designs previously dominated by Fairchild Semiconductor products before integration into onsemi.

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

Direct substitutes include other parts within the FAN2513 series with different fixed output voltages, such as FAN2513S27X for 2.7 V or FAN2513S26X for 2.6 V outputs. For lower current requirements, the FAN2511 series offers similar functionality with reduced output capacity. Ensure any replacement maintains the SOT-23-5 package and compatible pinout to avoid redesigning the printed circuit board.
