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

Verify the exact suffix 'S26X' against official onsemi documentation, as standard listings often reference variants like S25X or S27X. Confirm availability status, as this specific part number may be discontinued or superseded by newer revisions within the FAN2511 family. Ensure the datasheet matches the required 2.6 V output specification before procurement.

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

Select this component when a precise 2.6 V rail is required for sensitive analog or digital circuits in portable systems. The 100 mA current capability suits low-power applications, while the wide input range accommodates single-cell battery variations. Verify that the thermal performance in the SOT-23-5 package meets the system's dissipation requirements under maximum load conditions.

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

This device belongs to the FAN251x series of CMOS LDO regulators designed for cost-effective performance in portable communications equipment.
