The ISL9003AIENZ-T is a linear voltage regulator integrated circuit (IC) specifically designed for switchers who require a high-performance, efficient and customizable output power option. This device is capable of a maximum output current of 5A and is optimized for operating temperatures between –30°C and 85°C. This device is ideal for low-power electronic applications such as 5V inverters, clock-driven logic circuits, power measurements and systems requiring pre-regulators, under-voltage protection or voltage shifting.

In terms of current production (I LINE) this device can support up to 5A peak at 80°C, with a temperature coefficient of 0.2mV/°C for non-switching applications. The switching current design is quite similar, but with a slightly higher temperature coefficient of 0.3mV/°C. A push-pull output stage increases the linear regulation ability of the device, allowing for improved accuracy and small voltage overshoots.

The ISL9003AIENZ-T has been designed with a low standby current of only 45uA, which helps to ensure that the device meets the strict criteria for power cases when running in a continuous operating environment. In addition, the device features an adjustable reset threshold and an enable input, allowing for a high level of control over the output power. These features make the ISL9003AIENZ-T perfect for manning in applications where accurate, low power control is needed.

The operating mode of this device is selectable, allowing the user to choose from either continuous or discrete operation. The continuous operational mode is used when the device needs to deliver a constant, adjustable current without interruption. The discrete operational mode is used for purposes such as process control, pulse-width modulation or pulse-width modulation plus frequency modulation.

The ISL9003AIENZ-T linear voltage regulator is outstanding in the field of regulated power switching. Its adjustable reset threshold, current rating and discrete operation enable an incredibly precise level of control, making it an ideal device for applications such as 5V inverters, power measurements and logic circuit manning. The low standby current and operating temperature range of –30°C to 85°C make the ISL9003AIENZ-T an attractive choice for low-power electronics, and its adjustable output current rating makes it even more attractive for current-limited applications.
