NCP102 Datasheet, PDF (1/9 Pages) ON Semiconductor – Low Dropout Linear Regulator Controller

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 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.
