BAJ2DD0T

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

The BAJ2DD0T is a fixed-output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor, designed for applications requiring stable power delivery with high current capability. This component provides a fixed output voltage of 12V with a maximum output current of 2A. It operates within an input voltage range from 3V to 25V and withstands a maximum voltage of 35V. The device features a typical dropout voltage of 0.45V at full load and includes built-in thermal shutdown and over-current protection circuits. It is housed in a TO-220FP-3 package and 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 'T' corresponds to the tube packaging format as indicated in official documentation. Confirm RoHS compliance status and lead times directly with authorized distributors or ROHM sales representatives, as availability may vary due to end-of-life considerations mentioned in some sources. Ensure the ordering part number matches the exact electrical specifications required for your design.

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

Select this component when a fixed 12V output is required with up to 2A load current and low dropout performance is critical. Consider the TO-220FP-3 package for through-hole mounting and adequate heat dissipation. Verify that the input voltage remains within the 3V to 25V range and that the ambient temperature stays within -40°C to +125°C. Compare against similar BAxxDD0T series parts if different output voltages are needed.

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

The BAJ2DD0T belongs to ROHM's BAxxDD0T series of 2A fixed output LDO regulators. This series is characterized by its low-saturation PNP output transistor, which allows for minimal voltage drop between input and output. The components are designed for robustness with integrated protection features, making them suitable for demanding industrial and automotive environments where reliability and efficiency are paramount.

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

Direct substitutes within the same series include other BAxxDD0T variants with different fixed output voltages, such as BA18DD0T (18V) or BA15DD0T (15V), provided the voltage requirement differs. For equivalent functionality with slight parameter variations, verify compatibility with other 2A LDO regulators in TO-220FP packages from ROHM or other manufacturers, ensuring pinout and protection features match.
