S-8358B33MC-NQST2U

Overview

The S-8358B33MC-NQST2U is a step-up switching regulator IC from ABLIC, designed for low-power applications. It features a fixed 3.3 V output voltage and operates within an input voltage range of 0.9 V to 10 V. The device supports PWM/PFM hybrid control modes and maintains a typical quiescent current of 25.9 uA. It is housed in a compact SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates PWM/PFM hybrid control for optimized efficiency across varying load conditions.
• Features ultra-low standby current consumption suitable for battery-powered devices.
• Includes built-in protection mechanisms against over-current and thermal issues.

Applications

• Portable electronic devices requiring efficient power management
• Battery-operated sensors and IoT modules
• Consumer electronics with strict space constraints

Procurement Notes

Verify the exact suffix NQST2U against official ABLIC documentation to confirm pinout and packaging specifications. Ensure compatibility with your PCB footprint design. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement plans.

Selection Notes

Select this component when a fixed 3.3 V output is required from a wide input range. Consider the SOT-23-5 package size for space-limited designs. Evaluate the 25.9 uA quiescent current against system sleep requirements to ensure adequate battery life extension.

Part Context

This part belongs to the S-8358 series of step-up DC/DC controllers. It shares architectural similarities with other models in the family but differs in specific output voltage settings and package variants. The series is characterized by high integration and low power consumption.

Replacement Considerations

Direct substitutes include S-8358J33MC-NWST2U and S-8358F33MC-MKST2U, which offer identical electrical characteristics and pinouts. Verify package compatibility and operating temperature ranges before substitution.
