Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'SCBAZ' corresponds to the commercial temperature grade (0°C to +70°C) rather than the industrial grade (-40°C to +85°C). Confirm the package type is standard SOIC-8. Ensure compliance with RoHS directives matches project requirements. Cross-reference datasheet revision dates to confirm pinout consistency with legacy designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, low-cost inverting voltage solution is required for moderate current loads up to 45mA. It is suitable for applications where switching noise is manageable and efficiency is secondary to simplicity. Compare against industrial grade variants if operation below 0°C is necessary. Consider external capacitor selection carefully to maintain stability and minimize output ripple at the target load current.
