• Features ultra-low static current consumption to extend battery life in portable devices
• Includes built-in protection mechanisms against over-current and thermal overload conditions

Applications

• Battery-powered portable electronic devices requiring stable voltage regulation
• Consumer electronics utilizing single-cell lithium-ion or alkaline batteries
• IoT sensors and wireless modules needing efficient power management

Procurement Notes

Verify the specific suffix K8PT2U against official ABLIC documentation to confirm pinout compatibility and packaging specifications. Ensure that the ordering information matches the exact part number required for your design, as minor variations in suffixes can indicate differences in tape and reel configurations or regional compliance standards. Cross-reference with authorized distributors to validate authenticity and traceability.

Selection Notes

Select this component when a fixed 3 V output is required from a variable input source between 900 mV and 10 V. Consider the 231 mA output current capability and 50 kHz switching frequency for applications where moderate load currents and standard EMI profiles are acceptable. The SOT-23-5 package is ideal for space-constrained designs. Evaluate the 3 uA quiescent current against system sleep mode requirements to ensure optimal energy efficiency.

Part Context

This part belongs to the ABLIC S-8352 series of switching regulators, designed for general-purpose power management in mobile and industrial applications. The series offers various fixed output voltages and current ratings within the same footprint family. The S-8352D30MC variant specifically targets applications needing a reliable 3 V rail derived from lower voltage sources, maintaining performance across wide input ranges.

Replacement Considerations

Direct substitutes may include other ABLIC S-8352 series parts with identical output voltage and current ratings but different suffixes indicating package or tolerance variations. Verify electrical equivalence and pin compatibility before substitution.
