ISL6334AIRZ-TR5368 Voltage Regulator

ISL6334AIRZ-TR5368 is an integrated circuit (IC) voltage regulator and switching device. It is rated as a 6A and is a low dropout (LDO) voltage regulator, which is adjustable with an adjustable soft-start (optional). This part is suitable for a wide range of applications including power management of cell phones, laptops, set-top boxes, modems and data-loggers, as well as many embedded systems requiring precision voltage regulation.

Application Field

The ISL6334AIRZ-TR5368 voltage regulator is primarily used in DC-DC converters, computers, communication base stations, and automotive applications. ISL6334AIRZ can also be used for other applications such as providing auxiliary power for cell phones, laptops, set-top boxes, modems and data-loggers. It is also suitable for power management for embedded systems where precise voltage regulation is critical.

Working Principle

The ISL6334AIRZ-TR5368 voltage regulator is a 3 pin device which is able to regulate an input voltage from 0V to 6V. It features an adjustable output voltage, adjustable soft-start, a low-battery detect, and a power-on reset, which all help to ensure the system is properly controlled, reliable, and safe. The regulator has a dropout voltage of 0.5V and its output is adjustable from 0V to 6V with an accuracy of 0.25%.

The ISL6334AIRZ-TR5368 can operate with a maximum switch frequency of 500kHz and a minimum current limit of 10mA. Its internal logic is designed to operate over the full temperature range of -40C to +125C. The device also has over-current, over-temperature, and under-voltage lock-out protection. The device integrates a voltage supervisor that monitors the input voltage and asserts a power-on reset (POR) output, when the input voltage drops below a threshold.

The device has low power consumption and can operate in both continuous and pulse mode. In continuous mode, the device operates with a constant output voltage, limiting the output current to the value set by the current limit control. In pulse mode, the output voltage is modulated at 500 kHz, thereby providing lower average currents than would be provided in continuous mode. This regulation scheme is also more efficient at higher loads.

Overall, the ISL6334AIRZ-TR5368 is an excellent choice for a wide range of voltage regulator and switching applications. Its features make it suitable for powering various digital, analog, and communication applications. Its high efficiency and low dropout voltage make it ideal for applications where precise voltage regulation is necessary, or for applications that require a high level of energy efficiency.
