Introduction
The ISL9011AIRKFZ is an ultra-low power linear voltage regulator from Intersil, specifically designed for portable and extended-temperature applications. It’s a series of high-efficiency linear voltage regulators that offer excellent output voltage accuracy, low quiescent current, high power supply rejection ratio (PSRR), and good transient response. The ultra-low quiescent current and high efficiency ensure longer battery life and high reliability. This device is available in industry-standard TO-220, LVCSP and wafer-level chip-scale-packages (WCSP), making it an ideal choice for portable and industrial applications.Application of ISL9011AIRKFZ
The ISL9011AIRKFZ is widely used in a variety of consumer, industrial and automotive applications, including IoT, wearables, test and measurement systems, medical devices, consumer electronics, power management and communications equipment. Its ultra-low dropout voltage (<400 mV) allows the device to maintain a low drop-out voltage even when the input/output (Vio) is low. This makes it ideal for low voltage battery-powered applications. It’s also used in portable navigation devices, automotive powertrain systems and digital power supplies.The device provides high output accuracy of ±2% and low temperature coefficient (0.02%/°C) for a more reliable operation. It has a wide input voltage range of 1.4V to 6V, enabling the device to be used in various battery-powered applications. The low quiescent current (<1 μA) makes it an ideal choice for battery-powered applications that need extended battery life. The ISL9011AIRKFZ also features a low quiescent current of <0.6 μA and a high PSRR of 79 dB. This helps to minimize power consumption and electromagnetic interference (EMI).Working Principle of ISL9011AIRKFZ
The ISL9011AIRKFZ operates by transferring energy from an input voltage source to an output voltage. The device uses the Pulse-Width Modulated (PWM) control system, which monitors the input voltage and output voltage and adjusts the pulse width of the Pulse Frequency Modulator (PFM) to maintain the output voltage.When the input voltage is higher than the output voltage, the device switches off the output to maintain the output voltage. This results in an efficiency of up to 95%. When the output voltage drops below the reference voltage, the device turns on the output and supplies the difference between the input and output, ensuring the output voltage remains constant.The device also employs hysteresis characteristic that keeps the output voltage from oscillating between two voltage levels. The high PSRR of 79 dB enables the device to filter out noise from the input line and reduce supply noise. The high accuracy of ±2% ensures the output voltage remains constant regardless of the temperature changes.Conclusion
The ISL9011AIRKFZ is an ultra-low power linear voltage regulator from Intersil that offers excellent output voltage accuracy, low quiescent current and high power supply rejection ratio. The device is widely used in a variety of consumer, industrial and automotive applications, including IoT, wearables, test and measurement systems and digital power supplies. The device uses the Pulse-Width Modulated (PWM) control system and features a high PSRR of 79 dB, low temperature coefficient, and high accuracy of ±2%. The low quiescent current and high efficiency ensure long battery life and high reliability.The specific data is subject to PDF, and the above content is for reference
