ISL9011IRNFZ

Linear voltage regulators are critical components in Power Management Integrated Circuit (PMIC) circuits, providing the power requirements of various applications. The ISL9011IRNFZ linear voltage regulators are specifically designed to meet the stringent power requirements of the emerging digital and other high power components and modules. They provide up to 40-V output voltage and up to 600mA of output current with low ground current, making them ideal for a wide range of automotive and industrial applications.

The ISL9011IRNFZ linear voltage regulator is a dual-channel, voltage-mode, low-dropout (LDO) regulator that provides a robust and reliable power solution for high power applications. The device can be configured to provide up to 40-V output voltage, with up to 600mA output current capability. The low ground current in the ISL9011IRNFZ can be further improved to just 3µA. Furthermore, it features a wide range of operating temperature range between 0°C to 125°C, making it suitable for use in a wide range of automotive and industrial applications.

The ISL9011IRNFZ operates by utilizing a three-terminal shunt-regulator network, in which two bipolar transistors along with two current-sensing resistors are cascaded together between the output and ground terminals of the regulator. The third terminal, referred to as the adjust terminal, is connected to the base of the first transistor and serves as the voltage reference. The voltage reference is used to adjust the operating voltage of the regulator. When the load current is increased, the output voltage of the regulator is decreased, as the voltage reference is used as a control signal to adjust the output voltage. To maintain the voltage, a feedback loop is used to increase the current delivered to the load.

The ISL9011IRNFZ also incorporates a number of other features for optimal performance and reliability. It includes an adjustable soft-start function to reduce the start-up inrush current and ensure a smooth start-up. It also includes an output current limit feature to protect the device against overloads. It also features a temperature-compensated precision voltage reference (1.23V) and a power-on reset to ensure a clean power-on. Finally, the integrated thermal shutdown protection prevents the device from being damaged due to excessive operating temperatures.

The ISL9011IRNFZ linear voltage regulator is an ideal choice for automotive, industrial and medical applications. Automotive applications such as powertrain control units, exhaust systems, lighting, audio systems and many more require a reliable and robust power solution. Industrial and medical applications such as motor control and instrumentation require precise current control, and with its adjustable soft start and output current limit functions, the ISL9011IRNFZ can provide precision power control and reliable operation in these applications.
