SC2738IMSTRT

Overview

The SC2738IMSTRT is a dual linear FET controller manufactured by Semtech, designed for ultra-low output voltage applications. It operates within an input voltage range of 4.5 V to 13.2 V and provides adjustable outputs from 500 mV to 3.3 V with a maximum output current of 2 mA. The device features two positive output channels and utilizes an MSOP-10 surface-mount package. It functions across a temperature range of -40 °C to +85 °C, drawing a static current between 500 uA and 600 uA. The component includes a reference voltage of 500 mV and exhibits a load regulation of 3.5%.

Feature Summary

• Dual-channel architecture providing independent adjustable output control
• Ultra-low output voltage capability down to 500 mV
• Integrated N-channel MOSFET gate drive for external pass transistors

Applications

• Custom processor voltage regulation
• Bus termination voltage generation
• Logic level voltage supply

Procurement Notes

Verify the obsolete status of this component before design finalization, as it is listed as discontinued. Confirm that the MSOP-10 package dimensions align with your PCB layout constraints. Ensure the 2 mA output current meets your specific circuit requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Consider lead times for any remaining stock or alternative sourcing options due to end-of-life status.

Selection Notes

Select this controller when low dropout performance and precise low-voltage regulation are critical. The dual-output feature allows for simultaneous power rail generation. Verify that the external N-MOSFET selection matches the gate drive capabilities. Ensure the input voltage remains within the 4.5 V to 13.2 V operational window. Evaluate thermal dissipation requirements based on the load current and voltage drop across the external pass transistor.

Part Context

This component belongs to Semtech's line of linear regulator controllers, specifically optimized for low-power analog and digital circuits. It serves as a power management IC (PMIC) solution where efficiency and voltage precision are prioritized over high current delivery. The device complements other Semtech PMIC offerings by providing flexible voltage scaling for sensitive logic families.

Replacement Considerations

Public confirmed substitute part numbers were not identified in available documentation. Due to the discontinued status, verify compatibility with newer Semtech linear regulator controllers or equivalent dual-channel FET drivers from other manufacturers. Ensure pinout and electrical specifications match closely to minimize redesign efforts.
