NCP4587DMX31TCG

Introduction

The NCP4587DMX31TCG is a linear voltage regulator used in a variety of applications. It is specifically designed to power mobile and portable devices, including but not limited to mobile phones, tablets, GPS navigational systems, gaming consoles, and digital cameras. It is used to step down or regulate a higher voltage into a lower, more appropriate voltage. It is designed to accomplish this task without generating any unwanted noise or other undesirable characteristics. The NCP4587DMX31TCG is a stable device that operates at low-noise, low-power levels. It is capable of taking input voltages as high as 5.5V, producing a valid output voltage over a wide load range with a small footprint.

Operation

The NCP4587DMX31TCG linear voltage regulator is an adjustable voltage regulator that operates in a continuous conduction mode. The device has two internal transistors, a PMOS and an NMOS, that function as a current regulating switch. When current is requested from the output of the regulator, these transistors are allowed to move in the direction that allows current to pass. The device is designed to regulate the output voltage by steadily allowing the output to rise until the requested output voltage is met. This causes the load current to rise and the input voltage to fall.

The NCP4587DMX31TCG has a total of four features that are used to control its operation: Enable, Shutdown, Shutdown Delay, and Soft-Start. The enable feature is used to start and stop the regulator. When the enable pin is high, the regulator is started and when it is low, the regulator is shut down. The shutdown feature is used to turn the device off when a specified voltage is exceeded. The shutdown delay is used to set a time before the device turns off in case of a fault. Finally, the soft-start feature allows the output voltage to ramp up slowly from its lowest level instead of abruptly.

Applications

The NCP4587DMX31TCG is well-suited to a variety of applications. It is used in mobile and portable devices designed to powered by a variety of sources, including but not limited to mobile phones, tablets, GPS navigational systems, gaming consoles, and digital cameras. It is also used in a variety of designs with different operating voltages, including 12V and 24V systems, as well as with unregulated voltage sources. The device is designed to support input voltages as high as 5.5V, making it an ideal choice for automotive, industrial, and consumer applications.

The NCP4587DMX31TCG is also commonly used in conjunction with a power supply in order to increase its efficiency. This can be accomplished by connecting a device between the power supply and the voltage regulator. This device is used to store energy and supply it to the voltage regulator, which then uses it to stabilize the output voltage. This approach can be used to reduce power loss, increase efficiency, and reduce cost.
