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

Verify the specific suffix 'CTR' corresponds to the tape and reel packaging configuration required for your assembly line. Confirm that the 2.85V fixed output aligns precisely with your circuit design needs. Ensure compatibility with the 5-SSOP footprint during PCB layout. Check for any recent lifecycle status updates directly from the manufacturer before finalizing procurement plans.

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

Select this component when a precise 2.85V rail is required for automotive-grade circuits. The 100mA output current suits low-power peripherals rather than high-load drivers. Consider the 68dB PSRR for noise-sensitive analog sections. The inclusion of a shutdown pin allows for system-level power control integration.

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

This part belongs to the BU2JJA2 series of CMOS LDO regulators designed specifically for automotive electronics. The series emphasizes high reliability and compact form factors suitable for space-constrained vehicle interiors. It complements other variants in the family offering different voltage outputs while maintaining consistent protection features and package styles.

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

Direct substitutes include other BU2JJA2DG-CTR units with identical electrical specifications. Cross-referencing with similar ROHM parts like BU1CJA2DG-CTR requires verifying output voltage differences. Ensure any replacement maintains the AEC-Q100 qualification if automotive compliance is mandatory.
