NCP663SQ25T1

Analog devices, such as the NCP663SQ25T1, are the cornerstone of power management integrated circuits (PMICs) for multi-channel voltage regulation applications. Voltage regulators are used to control the current output of a power supply to a predetermined value that corresponds to the load within the system.

The NCP663SQ25T1, an SOT-233 package PDIP/SOIC N-Channel Low-side configured linear Voltage Regulator, acts as a low drop-out (-0.45 V) voltage regulator to control the output from the power supply to match the loads. This low voltage regulator has a low quiescent current of only 2.1 mA and requires only two external components for proper operation. It provides excellent load and line regulation of 0.1%, and offers a wide input voltage range of 3V to 28.5V.

The NCP663SQ25T1 offers a low shutdown current of 20 μA and fast transient response, allowing it to switch quickly to an output voltage that will accurately control the power supply current. This is advantageous in automotive and industrial applications that require precise control of the power supply output current to protect the system components from overvoltage and thermal damage. Also, it incorporates current limit as well as short circuit protection to ensure that the product will operate safely in a range of applications.

The NCP663SQ25T1 is ideal for use in systems such as battery-operated devices and point-of-load regulation, applications requiring precise current control, and automotive electronics systems. It can be used with a 3.3V to 28V input voltage range, and can be connected as an adjustable output with an external resistor divider.

The device also takes advantages of excellent performance and low power consumption. This Voltage Regulator is internally compensated for stable operation, with fast transient response to load disturbances and input voltage transients. The high-performance current limit circuit will protect the device against excessive current loads.

The NCP663SQ25T1 is a low drop-out (LDO) voltage regulator that can be configured either as a fixed output voltage device or as an adjustable output voltage device with the enable pin (control pin). When configured as a fixed output voltage device, the enable pin can be used to turn the regulator on or off.

When configured as an adjustable voltage device, the control pin enables the internal control loop. In this configuration, the output voltage is determined by an external resistor divider, with an output voltage range of 1.2V to 20V. This allows the user to customize the output voltage and current to the specific requirements of the application.

In summary, the NCP663SQ25T1 is an ideal voltage regulator for multi-channel voltage regulation applications. It features a wide input voltage range from 3V to 28.5V, low quiescent current of 2.1mA, excellent load and line regulation of 0.1%, and a low shutdown current of 20 μA. It is internally compensated for stable operation, with fast transient response to load disturbances and input voltage transients. It also provides short circuit protection so that the product can operate safely in a range of applications.
