NCP4523G3T1

Overview

The NCP4523G3T1 is a CMOS triple-channel low-dropout (LDO) regulator designed for RF unit applications. It provides three fixed output voltages: Channel 1 at 3.0V, Channel 2 at 2.8V, and Channel 3 at 2.35V. The device operates within an input voltage range of 3.5V to 6V. It is housed in an SSOP-8 package with dimensions of 3.0mm x 3.0mm. The component is supplied in tape and reel packaging with a quantity of 3000 units per reel.

Feature Summary

• Integrates three independent LDO channels in a single compact package
• Optimized for power management in RF unit circuits
• CMOS technology ensures low quiescent current operation

Applications

• RF unit power supply systems
• Multi-voltage digital logic powering
• Portable electronic devices requiring multiple regulated rails

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that the specific output voltage configuration (3.0V, 2.8V, 2.35V) matches the design requirements. Check for available substitute parts from onsemi or third-party vendors if production continuity is required. Ensure the SSOP-8 footprint compatibility with existing PCB layouts.

Selection Notes

Select this part only when three distinct fixed voltage outputs are needed within a narrow input range of 3.5V to 6V. The fixed outputs eliminate external resistor programming but limit flexibility. Consider thermal performance and load current capabilities relative to the RF application's power budget. Verify that the SSOP-8 package size fits the spatial constraints of the target device.

Part Context

The NCP4523G3T1 belongs to the NCP4523 series of special purpose regulators by onsemi. This series targets applications requiring multiple stable voltage rails from a single source. The G3 suffix indicates the specific voltage combination and package type. As an integrated solution, it reduces board space compared to discrete regulators.

Replacement Considerations

The manufacturer lists this part as obsolete. Evaluate equivalent triple-channel LDOs from onsemi or other manufacturers. Ensure replacement parts match the input voltage range, output voltages, and SSOP-8 package dimensions. Verify pin-to-pin compatibility to minimize PCB redesign efforts.
