Introduction to NCP717CMX285TBG

NCP717CMX285TBG is an advanced, low quiescent current linear regulator designed for battery powered and low power applications. It has an output voltage of 2.85V with excellent load and line regulation, low dropout and an internal overcurrent protection circuit. This device features a simple set up with an external resistor connected between the ground and RTrim pins. The NCP717CMX285TBG also has a low-noise output and can drive up to 1A of current.

Applications/Functionality

The NCP717CMX285TBG is ideal for battery powered applications such as portable media players, digital cameras, and smart phones due to its low dropout voltage and low quiescent current. The internal overcurrent protection circuit ensures that the device will not be damaged in the event of a short circuit.

The NCP717CMX285TBG is also useful for applications that require precision lower voltage outputs such as VRMs, microcontrollers and motor control applications. It can be used to provide a clean and stable output voltage that is adjustable with an external resistor connected between the ground and RTrim pins.

Working Principle

The NCP717CMX285TBG operates using a basic voltage regulator topology with a series control element. This element is comprised of an external resistor connected between the ground and RTrim pin, which will set the output voltage. The output voltage is then regulated by the internal error amplifier and P-channel MOSFET pass element.

An internal current limit circuit provides protection against overcurrent conditions and will reduce the error amplifier output voltage to shut off the pass element. The low quiescent current allows for accurate gain and output voltage. It also guarantees good line and load regulation.

Conclusion

The NCP717CMX285TBG is an advanced, low dropout linear voltage regulator designed for low-power applications. It has an output voltage of 2.85V with excellent load and line regulation, low dropout and an internal overcurrent protection circuit. The device is ideal for battery-powered applications due to its low quiescent current, and can also be used to provide a clean and stable output voltage in VRM, microcontroller, motor control and other applications.
