BAJ2DD0WT

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

The BAJ2DD0WT is a fixed-output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 12V output with a maximum current capacity of 2A. The device operates within an input voltage range of 3V to 25V and features a typical dropout voltage of 0.45V at full load, with a maximum of 0.7V. It utilizes a TO-220FP-5 package for through-hole mounting. Key electrical characteristics include a line regulation of 0.05% and a load regulation of 0.2%. The component supports an operating temperature range from -40°C to +125°C.

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

Verify the specific suffix 'WT' against the manufacturer's official datasheet to confirm pinout configuration and package type. Ensure the required 12V fixed output matches the application design. Confirm RoHS compliance status if environmental regulations apply. Check for end-of-life notices as some variants in this series may be discontinued.

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

Select this component when a fixed 12V output at up to 2A is required with low dropout performance. The TO-220FP-5 package suits applications needing robust thermal dissipation without active cooling. Consider the 0.45V typical dropout for efficiency optimization in battery-operated devices where input voltage margin is limited.

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

This part belongs to the BAxxDD0WT series of 2A fixed output LDO regulators with shutdown switches. The series offers various fixed output voltages and packages. The BAJ2DD0WT specifically denotes the 12V output variant in the TO-220FP-5 package. It shares core protection features like over-current and thermal shutdown with other members of the family.

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

Direct substitutes include other parts from the BAxxDD0WT series with different output voltages but identical pinouts, such as BAJ0CC0WT or BAJ6DD0WT, provided the voltage requirement differs. Verify that the replacement maintains the same 2A current rating and TO-220FP-5 package compatibility.
