SC1548CSK1.5TRT

Overview

The SC1548CSK1.5TRT is a single linear FET controller from the Semtech SC154 series, classified as a low-dropout voltage controller. It operates within an input voltage range of 11.28 V to 12.72 V and provides a fixed output voltage of 1.515 V. The device supports an output current of 10 mA with a quiescent supply current of 1 mA. Designed for surface-mount installation in an SOT-23-5 package, it functions reliably across a temperature range of 0°C to +70°C.

Feature Summary

• Single channel linear FET controller architecture
• Fixed output voltage regulation capability
• Low quiescent supply current operation

Applications

• Systems requiring stable 1.5V rail from ~12V source
• Battery-powered devices with high input voltage tolerance
• Embedded control circuits needing low noise power

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance details via official documentation. Ensure storage conditions meet semiconductor handling standards to prevent degradation. Validate pinout compatibility with existing PCB footprints before integration.

Selection Notes

Select this component when a fixed 1.515 V output is required from a narrow 11.28–12.72 V input window. Consider the 10 mA output limit and SOT-23-5 package constraints. Evaluate thermal performance within the 0°C to +70°C operating range against system requirements.

Part Context

Part of the SC154 series, focusing on linear FET controllers for precise voltage regulation. Designed for applications needing stable low-voltage rails from higher input sources with minimal external components.

Replacement Considerations

No public confirmed substitute part numbers are available. Verify functional equivalence carefully if considering alternatives from other manufacturers.
