The NCP102 is a low dropout linear regulator controller for applications requiring high-current and ultra low dropout voltages. The use of an external N-Channel MOSFET allows the user to adapt the device to a multitude of applications depending on system requirements for current and dropout voltage. An extremely accurate 0.8 V (+/-2%) reference allows the implementation of sub 1 V voltage supplies. The reference is guaranteed over the complete supply and temperature ranges. Other features of the NCP102 are a dedicated enable input,internally compensated error amplifier and an adjustable soft-start. A minimum drive capability of +/-5 mA provides fast transient response. The drive current is internally limited to protect the controller in case of an external MOSFET failure. The NCP102 is packaged in a space saving TSOP-6.
