The ISL9003IEJZ-T has a wide operating temperature range of −40°C to +125°C and provides an output voltage range of ±1.2V to +22V. It offers an actively adjustable output voltage from 0.6V to18V at currents up to 1A. This regulator also uses a PNP transistor inside to provide over-temperature protection.
The ISL9003IEJZ-T is ideal for use in a variety of applications and in particular where low-power, high-precision and low-emissions are required. It is a great choice for use in Personal Computer, Graphics card, HDD and other digital equipment applications.
Working Principle
The ISL9003IEJZ-T linear voltage regulator works on a simple but effective principle. This involves a voltage reference, an error amplifier, an output filter, and a series pass element.
The voltage reference sets the output voltage of the regulator, and it is usually a stable, temperature independent voltage. This voltage reference is fed into the error amplifier, which compares it to the input voltage, and produces an output that causes the output voltage to match the reference voltage.
The error amplifier’s output is sent to the output filter, which distributes the load and reduces the ripple output by the regulator. The output filter also prevents any sudden current fluctuations in the output voltage.
The output of the filter is then sent to the pass element, which adjusts the current between the input and the output to keep the output voltage within the desired range. The pass element also contains circuitry which provides protection against over-voltage, under-voltage, over-temperature and other conditions.
Conclusion
The ISL9003IEJZ-T linear voltage regulator is the ideal choice for applications requiring a low-power, high-precision regulator with low emissions. Its wide range output capability makes it suitable for a variety of applications. Moreover, its over-temperature protection feature ensures that the regulator does not overheat.
