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

This part belongs to the ILC7010 series of ultra-low noise LDO regulators from Fairchild Semiconductor. The series utilizes proprietary CMOS technology to combine low quiescent current with high ripple rejection. Other variants in the family offer different fixed output voltages such as 2.8V, 3.0V, 3.6V, 4.7V, and 5.0V, all sharing the same compact SC70-5 package and electrical architecture.

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

Direct substitutes include other ILC7010 variants with different fixed output voltages if the system voltage requirement changes. Cross-referencing with equivalent 80mA ultra-low noise LDOs in SC70-5 packages from other manufacturers requires verification of pinout compatibility and noise specifications.
