UCC3837D Description
The UCC3837D Linear Regulator Controller includes all the features required for an extremely 1ow dropout linear regulator that uses an external N-channel MOSFET as the pass transistor. The UCC3837D can operate from input voltages as 1ow as 3V and can provide high current levels thus providing an efficient linear solution for custom processor voltages, bus termination voltages, and other 1ogic level voltages below 3V. The onboard charge pump creates a gate drive voltage capable of driving an external N-MOSFET which is optimal for 1ow dropout voltage and high efficiency. The wide versatility of this IC allows the user to optimize the setting of both current 1imit and output voltage for applications beyond or between standard 3-terminal linear regulator ranges.
