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

Verify the specific suffix CE2 matches the required automotive qualification and packaging format. Confirm the TO-252-3 package variant aligns with PCB layout constraints. Ensure the AEC-Q100 certification meets project reliability standards. Check for any RoHS compliance documentation if required by regional regulations. Validate that the fixed 3.3V output suits the target load requirements without external adjustment.

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

Select this component when a robust, automotive-grade LDO with high voltage tolerance is needed. The 35V withstand voltage allows direct connection to battery lines or noisy automotive networks. The 1A output capability supports moderate load currents common in infotainment or sensor modules. Consider the TO-252-3 package for efficient thermal dissipation in compact designs. Verify that the fixed output voltage matches the system requirement precisely.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to ROHM's automotive LDO series, specifically engineered for high-voltage automotive environments. It complements other BD33 variants by offering enhanced ruggedness and integrated protection features. The family focuses on reliability and safety compliance for critical vehicle subsystems. It serves as a key power management solution where standard industrial regulators may fail due to harsh electrical conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

The BD33FC0FP-E2 is a similar 1A LDO but lacks the explicit automotive functional safety support mentioned for the CE2 variant. Verify if the FS supportive classification is mandatory for the application before substituting.
