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

Verify the specific suffix CE2 against the manufacturer's latest datasheet to confirm packaging type and reel specifications. Ensure the procurement channel provides original documentation to validate AEC-Q100 compliance status. Cross-reference the part number with official ROHM databases to avoid counterfeit components, as automotive grades require strict traceability and quality assurance protocols during sourcing.

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

Select this component when a fixed 5 V output is required with high input voltage tolerance up to 26.5 V. The TO-263-3 package offers superior thermal dissipation compared to smaller footprints, making it suitable for 1 A continuous load applications. Consider the 300 mV dropout voltage for efficiency optimization in battery-powered or alternator-fed automotive systems where input voltage may fluctuate near the output level.
