ISL9014AIRLLZ-T Application Field and Working Principle

The ISL9014AIRLLZ-T is a linear, adjustable, low-dropout (LDO) negative-wave, positive-wave voltage regulator with low quiescent current and low differential errors over temperature. This device is offered in a small, surface-mount package, making it ideal for a variety of cost-sensitive and space-sensitive applications. This device can provide excellent current- and temperature-regulated output with very low dropout voltage, making it an ideal choice for a variety of low voltage applications where space and cost are of primary concern. Additionally, the device can be used for secondary power supply in automotive applications and in battery-powered applications.

The ISL9014AIRLLZ-T is designed to provide power in a variety of applications, including: interconnects, low-power sensors, running on 1.8V to 5V, as well as providing a power supply for up to 12V at 1A in 3.3V/5V systems. This device is also versatile, providing flexible output voltage regulation between -0.02V to -17V, with an adjustable voltage of 1.8V to 12V.

The ISL9014AIRLLZ-T linear voltage regulator is a modern, fixed, adjustable regulator device. Its operating principle is based on the standard Zener effect, in which the voltage is regulated by passing a small current through a semi-conductor material and allowing a large current to flow once the voltage reaches the set point. The advantages of the ISL9014AIRLLZ-T are that it can provide a very low quiescent current and does not require an external power-conversion component, making it ideal for cost-sensitive and space-sensitive applications. Additionally, its low dropout voltage makes it perfect for applications needing a regulated voltage lower than the input voltage.

The operating characteristics of the ISL9014AIRLLZ-T are based on an error amplifier which is a single external resistor and capacitor; this amplifies the difference between the reference voltage and the input voltage. It then makes the necessary adjustments to the output voltage to maintain a lower reference voltage. The device has very low output impedance, allowing it to maintain a constant voltage even when the load current varies. The ISL9014AIRLLZ-T is stable at temperature, providing constant output voltage with only ±2.5mV of differential error across the temperature range.

The ISL9014AIRLLZ-T is a versatile device, offering a wide range of output voltages, adjustable current limit and built-in thermal overload protection. It can be used in a wide range of applications, such as distributed power supply systems, load switching, microprocessor power supplies and portable devices. It is suitable for automotive, low-voltage systems, handhelds, and medical equipment.

In summary, the ISL9014AIRLLZ-T from Intersil is a high-performance, adjustable, low-dropout linear voltage regulator capable of supplying up to 1A low quiescent current and low differential errors over temperature. Its adjustable output voltage range of 1.8V to 12V makes the device suitable for a wide range of cost-sensitive and space-sensitive applications. Its low dropout voltage and low output impedance make it an ideal choice for applications requiring a regulated voltage lower than the input voltage. Additionally, it has built-in thermal protection, providing reliable performance even in adverse conditions.
