NCP4523G20T1

Overview

The NCP4523G20T1 is a fixed positive LDO regulator featuring three independent output channels. It provides specific voltage levels of 2.35V, 2.8V, and an additional regulated output, designed for CMOS applications. The device is housed in an 8-LSSOP or 8-MSOP package with dimensions of 0.110 inches (2.80mm). It operates within a temperature range of -40°C to 85°C and is specifically engineered for RF unit power management.

Feature Summary

• Provides three distinct fixed output voltages for multi-rail requirements
• Optimized for low-noise RF unit power supply applications
• Utilizes compact surface-mount packaging for space-constrained designs

Applications

• RF unit power distribution
• Multi-voltage CMOS circuit powering
• Communication module bias supplies

Procurement Notes

Verify the exact suffix and manufacturer status as this component may be discontinued or available through secondary distributors like Rochester Electronics. Confirm package type compatibility and thermal performance against current design requirements before procurement.

Selection Notes

Select this part when three specific fixed voltages are required for RF circuits. Ensure the load current does not exceed the regulator's limits. Consider the operating temperature range and package thermal resistance for proper heat dissipation in the final assembly.

Part Context

This component belongs to onsemi's linear regulator portfolio, specifically targeting analog and mixed-signal applications. It serves as a dedicated power solution for radio frequency systems requiring stable, low-noise voltage rails from a single input source.

Replacement Considerations

Check for direct pin-compatible alternatives if this part is no longer manufactured. Verify that substitute regulators match the output voltage tolerances and package dimensions to ensure seamless integration into existing PCB layouts.
