Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (Z or P) to confirm package type and reel quantity before ordering. Confirm AEC-Q100 compliance requirements match your design specifications. Check lead times as production cycles may vary significantly between variants. Ensure thermal management aligns with the SOIC-8 package capabilities for your intended load conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing for automotive environments requiring wide input voltage ranges up to 75 V. Choose the Z variant for standard SOIC-8 packaging or the P variant if SOIC-EP-8 is required. Consider the 300 mA limit for low-power peripheral supplies. Verify that the 20 uA quiescent current meets standby power constraints.
