S-8357F50MC-MHJT2G

Overview

The S-8357F50MC-MHJT2G is a step-up switching regulator controller from ABLIC's S-8357 series. It provides a fixed output voltage of 5.0 V with a tolerance of 2.4%. The device operates at a switching frequency of 300 kHz and delivers an output current of 54.8 mA. It functions within an input voltage range of 0.9 V to 10 V, consuming a typical quiescent current of 25.9 µA. The component supports operation between -40°C and +85°C and is housed in a compact SOT-23-5 package.

Feature Summary

• Integrates a boost converter topology for efficient voltage step-up applications
• Features low power consumption suitable for battery-operated systems
• Utilizes PWM control for stable output regulation

Applications

• Portable electronic devices requiring voltage boosting
• Battery-powered sensor modules
• Low-power consumer electronics

Procurement Notes

Verify the specific suffix MHJT2G against official ABLIC documentation to confirm exact tape-and-reel specifications and marking codes. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Cross-reference RoHS compliance status directly with the manufacturer's latest product change notifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5.0 V output is required from a single-cell lithium-ion or similar low-voltage source. The 300 kHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Consider the 54.8 mA output limit to ensure it meets load requirements without exceeding thermal constraints in the SOT-23-5 package.

Part Context

This part belongs to the S-8357 series of non-isolated DC-DC converters. The series offers various fixed output voltages and packaging options. The S-8357F50 variant specifically targets applications needing a precise 5.0 V rail with moderate current capabilities, distinguishing it from higher-current models in the same family.

Replacement Considerations

Direct substitutes include other S-8357 series parts with identical pinouts but different output voltages, such as S-8357F36MC-MHJT2G. Verify that alternative packages like MKST2U are mechanically compatible if form-factor changes are permissible.
