DESCRIPTION
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...
