Procurement Notes
Verify the exact part number against official ABLIC documentation to ensure compatibility with your design requirements. Confirm package type and operating temperature range match your application specifications. Check for RoHS compliance status if required by your manufacturing standards. Ensure sourcing channels provide genuine components to avoid counterfeit risks.
Selection Notes
Consider the fixed 3.8 V output when designing circuits that require this specific voltage level. Evaluate the 25.9 mA output current capability against your load requirements. Assess the 300 kHz switching frequency impact on external component selection and electromagnetic interference. Verify input voltage range compatibility with your power source characteristics.
Part Context
This component belongs to the S-8357 series of step-up switching regulators from ABLIC Inc. The series offers various fixed output voltage options to suit different application needs. These regulators are designed for portable devices where efficiency and small footprint are critical. The S-8357 series typically integrates protection features and operates with minimal external components.
Replacement Considerations
Check ABLIC's official documentation for direct replacements within the S-8357 series with different output voltages. Consider other manufacturers' step-up regulators with similar electrical characteristics if pin compatibility is not required. Verify functional equivalence before substitution to ensure circuit performance remains unaffected.
