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

Verify the specific suffix configuration when sourcing this component, as ordering codes determine the exact package type and shipping format. Confirm that the procurement channel provides official datasheets matching the BAxxCC0WT series specifications. Ensure the received units match the physical pinout and marking diagrams provided in the manufacturer documentation to avoid integration errors.

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

Select this regulator when a stable 12V rail is required with up to 1A capacity and system power-down capabilities are necessary. The TO220FP-5 package facilitates thermal dissipation for moderate power applications. Consider the input voltage headroom relative to the dropout characteristics to ensure regulation stability across the full operating temperature range and load conditions.

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

This component belongs to the BAxxCC0WT series of standard fixed output LDO regulators produced by Rohm Semiconductor. The series offers various fixed voltage options ranging from 3.0V to 15.0V, all sharing similar protection features and package options. The 'W' designation indicates the inclusion of a shutdown switch, distinguishing it from non-switch variants within the broader BAxxCC0 family.

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

Compatible substitutes include other parts from the BAxxCC0WT series with different output voltages, such as BAJ0CC0WT or BA09CC0WT, provided the voltage requirement differs. Cross-series replacements like the BAxxDD0WT offer higher current capacity but may require verification of pin compatibility and thermal performance adjustments.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How does the shutdown switch function operate on this regulator?

The shutdown switch is controlled via the CTL terminal. Applying a voltage of 2.0V or higher activates the output, while a voltage of 0.8V or lower disables it, reducing the shutdown current to approximately 0μA.

What protection mechanisms are integrated into the BAJ2CC0WT-V5?

The device incorporates built-in over-current protection to prevent damage from short circuits, a thermal shutdown circuit to protect against overheating, and an over-voltage protection circuit to guard against power supply surges.
