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

Verify the specific suffix 'AIC528X' against official Fairchild documentation to confirm the fixed 2.8V output voltage and packaging details. Ensure compatibility with required output capacitor ESR specifications to maintain stability. Confirm RoHS compliance status as indicated in the datasheet. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

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

Select this regulator when low noise and small size are critical for RF signal integrity. The 80mA current limit suits low-power portable devices rather than high-load applications. Consider the 2.8V fixed output if it matches the target circuit voltage requirements without needing external adjustment resistors. Evaluate thermal performance based on the expected voltage drop and load current in the final application.

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

This component belongs to the ILC7010 family of micropower CMOS RF LDO regulators. These devices utilize a proprietary CMOS process that combines low quiescent current with high ripple rejection capabilities. The family is designed to replace larger bipolar regulators in modern portable electronics, offering improved performance in a significantly smaller package size while maintaining stable operation with ceramic or tantalum capacitors.

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

Direct substitutes include other ILC7010 variants with different fixed output voltages, such as ILC7010AIC525X (2.5V) or ILC7010AIC526X (3.0V), provided the system voltage requirement changes. Generic replacements must match the 80mA output current, SC-70 package, and low-noise specifications. Verify pinout compatibility before substitution.
