Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'D' corresponds to the 8-pin SOIC package and tape-and-reel quantity when ordering. Confirm that the Q1 designation meets your organization's automotive quality standards. Ensure the input voltage does not exceed the 40 V absolute maximum rating during transient conditions. Check for moisture sensitivity level requirements prior to surface mount assembly.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5 V rail is required from a high-voltage source with minimal standby drain. The integrated sense feature allows for remote voltage regulation to compensate for trace resistance. Consider the thermal performance of the SOIC package under continuous 150 mA load conditions. This regulator is suitable for applications requiring AEC-Q100 qualification and robust high-voltage tolerance.
