Description

UCC2837NG4 Description
All the features needed for an extremely low dropout linear regulator that uses an external N-channel MOSFET as the pass transistor are included in the UCC2837NG4 Linear Regulator Controller. An effective linear solution for custom processor voltages, bus termination voltages, and other logic level voltages below 3V is provided by the device since it can operate from input voltages as low as 3V and can offer high current levels. When driving an external N-MOSFET, the on-board charge pump generates a gate drive voltage that is ideal for low dropout voltage and good efficiency. The extensive adaptability of this IC enables the user to optimize the setting of the output voltage and current limit for applications outside of or within the typical limits of a 3-terminal linear regulator. This 8-pin controller IC uses a duty ratio current limiting approach that limits the average power dissipation of the pass transistor under fault conditions while providing peak transient loading capacity.

The UCC3837 Linear Regulator Controller includes all the features required for an extremely low dropout linear regulator that uses an external N-channel MOSFET as the pass transistor. The device can operate from input voltages as low as 3V and can provide high current levels, thus providing an efficient linear solution for custom processor voltages, bus termination voltages, and other logic level voltages below 3V. The on board charge pump creates a gate drive voltage capable of driving an external N-MOSFET which is optimal for low dropout voltage and high efficiency. The wide versatility of this IC allows the user to optimize the setting of both current limit and output voltage for applications beyond or between standard 3-terminal linear regulator ranges. This 8-pin controller IC features a duty ratio current limiting technique that provides peak transient loading capability while limiting the average power dissipation of the pass transistor during fault conditions.
