SCV303LSN46T1G

Supervisors Overview

The SCV303LSN46T1G is a high-performance, low-dropout (LDO) voltage regulator manufactured by onsemi. It provides a fixed output voltage of 4.6V with a maximum load current capability of 300mA. The device features ultra-low noise characteristics, making it suitable for sensitive analog and RF circuits. It includes built-in protection mechanisms such as thermal shutdown and current limiting to ensure reliable operation under various load conditions.

Supervisors Feature Summary

• Ultra-low noise performance for sensitive signal integrity
• Fixed 4.6V output voltage option
• Integrated thermal shutdown and current limit protection

Supervisors Applications

• RF front-end modules requiring clean power supplies
• Portable electronic devices with strict noise requirements
• Sensor interfaces in automotive or industrial systems

Supervisors Procurement Notes

Verify the exact suffix 'T1G' matches your bill of materials, as it denotes specific tape-and-reel packaging and lead-free compliance. Confirm the 4.6V output variant is required, as other voltages may exist in the same family. Ensure the operating temperature range aligns with your system design specifications before finalizing procurement.

Supervisors Selection Notes

Select this component when low noise is critical for downstream circuitry. The 300mA current rating suits moderate load applications. Consider the SOT-89-3 package constraints for thermal management. Verify input voltage ranges exceed the dropout voltage at maximum load to maintain regulation stability.

Supervisors Part Context

This part belongs to onsemi's SCV series of LDO regulators, designed for efficiency and noise reduction. It complements higher-current variants in the lineup, offering a balance between power delivery and signal purity for compact designs.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the SCV series if supply chain issues arise. Ensure any substitute maintains the 4.6V output and similar noise specifications. Verify package compatibility to avoid PCB redesign efforts.
