LFC789D25CPW Description

A dual linear FET controller called the LFC789D25 makes it easier to create dual power supply. A low-dropout regulator is implemented by the device's two independent controllers, each of which drives an external MOSFET. A tracking regulator, which is frequently required for termination schemes, can be created by programming the second controller to regulate any desired output voltage via a reference input pin while the first controller is configured to regulate a fixed 2.5-V output. Additionally, the controllers can manage the output voltages to a maximum tolerance of 2% across temperature and load due to the ease with which the heating effects of the external FETs can be readily segregated from the controllers.

LFC789D25CPW Features

• A Tracking Regulator Can Be Made by Adjusting the Output Using an External Reference Pin.

• Excellent Flexibility in Design with Few External Components
