NCP102 Low Dropout Linear Regulator Controller 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 suppl

NCP102 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 i
