Introduction

ISL9003AIEKZ-T is a linear voltage regulator, which can provide up to 10A maximum current with 1.5V to 7V adjustable output voltage. It is suited for integration in portable, mobile and battery powered devices, such as tablets, cellular phones, digital cameras and more. The device is designed to provide low quiescent current and high power supply rejection ratio (PSRR) ensuring an efficient and reliable power supply. ISL9003AIEKZ-T is a versatile device that can be used for different applications.

Features

ISL9003AIEKZ-T linear voltage regulator features an adjustable output voltage from 1.5V to 7V and a maximum current rating of 10A. It is designed to provide low quiescent current, with a maximum rating of 170µA. The device has an ultra-high PSRR of up to 75dB, which provides a low-noise power supply, even in noisy environments. It also features short-circuit protection, thermal shutdown and over-voltage protection.

Application Field

ISL9003AIEKZ-T can be used in a wide range of applications including tablets, Cellular phones, digital cameras, gaming devices, MP3 players, industrial and medical equipment, and automotive electronics. The high PSRR of 75 dB ensures an efficient, low-noise and reliable power supply in noisy environments. It also has short-circuit protection and thermal shutdown protection, which will prevent it from over-heating in extreme situations. Furthermore, with its wide adjustable output voltage range of 1.5V to 7V, the ISL9003AIEKZ-T can be used to provide different power supply voltages to different components in the same circuit.

Working Principle

The ISL9003AIEKZ-T has an operating voltage range of 5V to 36V and a maximum output current of 10A. The regulator uses an internal error amplifier that controls the final output voltage. The PWM controller compares the internal voltage reference with a feedback voltage from the output, and drives the power MOSFET in order to maintain the output voltage at the desired level. The device also features over-load, over-current and over-voltage protection, and will shut down in case of an abnormal situation. The protection circuit uses current sensing, which is done by connecting a sense resistor in series with the source of the MOSFET. If the output voltage deviates from the desired level due to an overload, the device will actively limit the current and switch off the output automatically.

Conclusion

The ISL9003AIEKZ-T linear voltage regulator is an ideal solution for portable, mobile and battery-powered applications. It has an adjustable output voltage range of 1.5V to 7V, a maximum output current of 10A and an ultra-high PSRR of up to 75dB, making it suitable for use in noisy environments. The device also features short-circuit protection and thermal shutdown protection, which will protect it from overheating. In conclusion, the ISL9003AIEKZ-T is an efficient and reliable device for providing a steady and low-noise power supply in a variety of applications.
