The ISL9003IEHZ-T is a regulator integrated circuit (IC) that regulates voltage in an electronic circuit. It falls under the category of power management integrated circuits (PMICs). Specifically, it\'s classified as a linear voltage regulator. This type of regulator operates by reducing a larger input voltage to a smaller output voltage in order to supply the necessary power to a load, such as a processor. The ISL9003IEHZ-T provides adjustable output voltage, offering flexibility in various applications.
ISL9003IEHZ-T Key Features and Parameters
The ISL9003IEHZ-T has several key features and parameters that determine its performance. Its typical input voltage range is 4.75V to 40V and its typical output range is 0.9V to 24V. The maximum output current is 1.5A, and it has a maximum operating temperature of 70°C. It also has integrated over-voltage protection and can support up to 2A of output ripple current. The ISL9003IEHZ-T has a low quiescent current consumption of 4.8mA in standby mode and a high efficiency of 87% at 1A output current.
ISL9003IEHZ-T Application Field and Working Principle
The ISL9003IEHZ-T voltage regulator is suitable for a wide range of applications, such as automotive, industrial, and consumer. It is commonly used as a power supply for microcontrollers, FPGAs, RF transceivers, and other electronic components that require a reliable and consistent voltage for proper functioning. It can also be used as a power supply for motors, lights, and other devices. Due to its adjustable output voltage, the ISL9003IEHZ-T is suitable for applications that require different voltage levels.
The working principle of the ISL9003IEHZ-T is fairly simple. It uses a series of transistors, resistors, and capacitors to reduce the input voltage to a desired output voltage. There are two critical components in the voltage regulator circuit: the series pass transistor, which modulates the current in the circuit, and the reference voltage source, which sets the output voltage. The transistor acts as the primary device to regulate the current, while the reference voltage source sets the output voltage. The series pass transistor switches on and off in order to keep the output voltage in check. As the load draws current, the current is monitored by the regulator and the series pass transistor is switched on and off to maintain the desired output voltage.
The ISL9003IEHZ-T offers excellent stability and reliability for various applications due to its adjustable output voltage and low quiescent current consumption. It offers protection from over-voltage, current limiting and short-circuit protection, making it a reliable power source for complex circuitry. Its integrated over-voltage protection prevents damage to connected devices due to over-voltage. The ISL9003IEHZ-T is an excellent choice for powering a wide range of electronic devices due to its robust design and excellent stability.
