S-8357G50MC-MJJT2G

Overview

The S-8357G50MC-MJJT2U is a non-isolated step-up switching regulator controller from the ABLIC S-8357 series. It utilizes Pulse Width Modulation (PWM) control to boost input voltages to a fixed 5.0V output. The device operates with a switching frequency of 300 kHz and supports a maximum duty cycle of 78%. It delivers an output current capability of 54.8 mA while maintaining a low operating supply current of 25.9 uA. The component is housed in a compact SOT-23-5 surface-mount package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates PWM control circuitry for efficient voltage boosting applications
• Features ultra-low operating supply current to minimize standby power consumption
• Utilizes a compact SOT-23-5 package for space-constrained designs

Applications

• Battery-powered portable electronic devices requiring voltage step-up
• Low-power sensor nodes needing stable 5V regulation
• Industrial equipment with limited power budgets

Procurement Notes

Verify the specific suffix against official ABLIC documentation, as distributor listings may contain typos or generic placeholders. Confirm the exact output voltage and package type match your schematic requirements before ordering. Ensure compliance with RoHS directives if required by your manufacturing standards.

Selection Notes

Select this component when a fixed 5V output is required from a lower input source. The 300 kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 54.8 mA output limit to ensure it meets the load requirements of the target application without exceeding thermal limits.

Part Context

This part belongs to the S-8357 series of switching regulators designed for high efficiency and low power consumption. The series offers various fixed output voltages and packaging options to suit different design constraints. It is categorized under PMIC switching controllers within the broader ABLIC portfolio.

Replacement Considerations

Check for other S-8357 variants with compatible output voltages and packages. Verify pinout compatibility if substituting with similar boost controllers from other manufacturers.
