BAJ2DD0WHFP-TR

BAJ2DD0WHFP-TR are voltage regulators from the Linear family.

Application Field

The BAJ2DD0WHFP-TR voltage regulator is intended to be used in rechargeable battery powered systems, including notebooks and subnotebooks. It provides low quiescent current and low dropout voltages. Its features include shutdown, multi-level voltage setting, current limiting, and thermal protection.

Working Principle

The BAJ2DD0WHFP-TR voltage regulator works in a 2-phase way. In the first phase, the device attempts to regulate the output voltage of the system by monitoring the load after current limiting has occurred. This is done by comparing the actual output of the system with the reference voltage. If the two signals do not match, the device further regulates the output voltage.

In the second phase, the device limits the output current by automatically shutting down the system if the output current exceeds its predetermined limit. This safety feature serves as an additional protection against overloads or short circuits that may occur during operation.

The device also features thermal protection which triggers shut-down if the temperature of the device reaches an elevated level. This helps prevent the device from being damaged in the event of an overload or short circuit.

The BAJ2DD0WHFP-TR voltage regulator combines both the above-mentioned phases of regulation and protection in one device, thus providing a cost-effective solution for battery powered systems.
