The ISL9008AIRUKZ-T is a high-performance voltage regulator, belonging to the Linear category of PMIC – Voltage Regulator range. This Regulator boasts of high regulations accuracy, low quiescent current and low output noise ripple, all at an affordable cost. It is capable of supplying both negative and positive output levels to meet the requirements of multiple applications such as two/three terminal adjustable regulator, battery charger, DC-DC converter, etc.

The main application field of the ISL9008AIRUKZ-T Voltage Regulator is in power supply design for wide variety of systems. This Regulator provides an output voltage from 2.5V to 15V. It is used in loads with output current up to 5A (max 8A). This Regulator can be used in systems with a 7V-45V supply voltage. Besides, its excellent line/load transient performance and low output ripple noise make it ideal for automotive, medical, communication and emerging applications in the field of robotic and intelligent systems.

The working principle behind the ISL9008AIRUKZ-T Regulator is simple: it provides a steady and constant output voltage regulated by a voltage comparator whose reference input of the regulator is determined in part by the value of the external resistor RT. The voltage difference between RT and the output voltage is then amplified and compared with an adjustable reference set by the on-chip Trim pin. When the output voltage deviates from its expected value, it causes the output of the voltage comparator to switch, which in turn triggers the correct number of pulses in external resistor to drive the switching/control transistor, thus adjusting the output voltage back to the expected value.

Furthermore, the ISL9008AIRUKZ-T Voltage Regulator features a slew rate controlled loop, allowing the use of a larger output capacitor and decoupling capacitor and further improving the line regulation performance. It also features over-temperature and cycle by cycle current limiting functions. Also, it has a wide overload protection span starting from ±10%, extending up to 150%.

To sum up, the ISL9008AIRUKZ-T Voltage Regulator is a robust and versatile PMIC – Voltage Regulator module, delivering high efficient and reliable performance at an affordable cost, making it the ideal choice for a wide variety of applications.
