Working Principle

The BAJ2DD0WT operates on a current-mode linear voltage regulator. This type of regulator uses an internal control circuit to regulate the output voltage of the regulator based on the current that passes through it. The current through the regulator is measured and compared with the set output voltage. If the measured current is higher than the set voltage, then the internal regulator reduces the output voltage to decrease the current flowing through the regulator. If the current is lower than the set voltage, then the output voltage is increased to bring the current back to the set level.This regulation of voltage is done by the internal control circuit which uses a reference voltage to compare the measured current with. The reference voltage is set using an external resistor and can be adjusted based on the desired output voltage requirement.

Conclusion

BJ2DD0WT is a high-precision current-mode linear voltage regulator from Texas Instruments tailored to meet the needs of a variety of applications. It features a wide range of input voltage, adjustable current limit, adjustable soft-start, and short-circuit protection. It is suitable for automotive, industrial and LED applications. The operating principle of the BJ2DD0WT is based on a current-mode linear voltage regulator which uses an internal control circuit to regulate the output voltage.
