ILC7083AIM530X Application Field & Working Principle

The ILC7083AIM530X is a low-dropout linear regulators (LDO) device from Infineon, based on a special integrated circuit that provides the user with high accuracy and low noise output of the system. It is suitable for wide range of applications such as post-PCB mounting, portable and low-power systems, or for low-power systems, where noise and stability are of high importance.

The ILC7083AIM530X has a wide range of input voltages from 0.9 V to 12 V, and a maximum output current of 550 mA. It has advanced short-circuit and over-current protection, and its output voltage remains stable even under high voltages and extreme temperatures. The device is also rated for a wide range of temperatures, from -40°C to +125°C, making it suitable for high temperature environments.

The ILC7083AIM530X can adapt to various load and input conditions, due to its high dynamic response rate and transient output current capability. It has two different modes for regulating the output voltage: normal, or phase-shift mode. The device also has programmable current limits, and a low noise output of 8.5 μVrms. The wide range of features, options and protections make this device suitable for many applications like notebook computers, automotive, equipment, handheld devices and consumer applications.

The ILC7083AIM530X is designed to provide a very precise voltage regulation, with a low drop-out voltage of only 0.3V, and a reference voltage accuracy of ±1%. It also has an internal limited cycle time protection, which prevents excessive output current during brief periods of over-power. Additionally, the device features power up sequencing, thermal protection, over-voltage protection, over-current protection and dissipation limiting functions.

The operating principle of the ILC7083AIM530X is based on an operational amplifier coupled with a PNPN MOSFET, which are used to regulate the output voltage. When the voltage on the input pin of the device exceeds the programmed output voltage, the PNPN MOSFET is turned on, which provides current to the ground side of the output, reducing the output voltage. This cycle continues until the output voltage reaches the desired value.

The ILC7083AIM530X is the perfect device for providing precise voltage regulation in a wide range of applications, with a low drop-out of 0.3 V and ±1% reference voltage accuracy. With its high dynamic response rate, programmable current limits, and various protections, this device is sure to provide an accurate output voltage, no matter what the conditions may be.
