ISL9011IRMMZ-T

The ISL9011IRMMZ-T is a low-dropout (LDO) linear voltage regulator specifically designed for applications requiring ultra-low power consumption, such as portable electronics, telematics, IoT-enabled wearable devices, and medical diagnostic and monitoring equipment. Its narrow supply voltage range, low quiescent current, and a shut-down current of less than 0.1µA make it suitable for applications operating on a single-cell Li-Ion battery or a supercapacitor/battery combo. It has very low dropout voltage and fast transient response, enabling stable regulation in applications with a wide input voltage range. The device is available in a 2mm x 2mm WDFN package.

The ISL9011IRMMZ-T is based on a low-dropout linear regulator architecture. The linear regulator works by combining an error amplifier, a driver transistor and a pass element in a feedback loop, which continuously monitors and compares the output voltage of the regulator to a reference voltage. The error amplifier then adjusts the drive current applied to the pass element, which regulates the output voltage. This architecture is relatively simple and efficient compared to other voltage regulation architectures, and is suitable for applications with low output currents. The ISL9011IRMMZ-T has an adjustable output voltage range of 1.2V–3.6V, and can provide up to 150mA current.

The ISL9011IRMMZ-T features a high PSRR (power supply rejection ratio) of 72dB at 1kHz, which helps to reduce noise at the output. The accuracy of the output voltage is guaranteed over –40ºC to +125ºC temperature range by a ±0.5% accuracy specifications. The device also includes a wide range of protection features such as thermal protection, current limit protection, output voltage slew protection, and adjustable reverse current protection, ensuring reliable operation of a system. It also has an enable pin that allows it to switch between a low- power mode and an off mode, providing an additional level of energy savings.

The ISL9011IRMMZ-T is a versatile voltage regulator solution for portable consumer, industrial and medical equipment. Despite its small size, it can provide the performance and reliability needed in those applications. Its low power consumption and wide range of protection features make it suitable for battery-powered systems, which require reliable operation over long periods of time.

In summary, the ISL9011IRMMZ-T is a low-dropout linear voltage regulator designed for ultra-low-power applications. It features an adjustable output voltage range, a high PSRR, and a wide range of protection features. The device is suitable for a variety of portable consumer, industrial and medical applications, providing performance and reliability over a long period of time.
