Key Featrues
Guaranteed 500mA Output Current: With a guaranteed output current of 500mA, the device ensures reliable power delivery for demanding loads, such as microprocessors, DSP cores, and I/O power systems. This capability enhances its suitability for high-performance applications without compromising stability.
Low Quiescent Current (28µA): The quiescent current of just 28µA minimizes power consumption during idle or light-load conditions, improving overall energy efficiency. This is particularly beneficial for battery-powered devices, extending their operational life.
Factory-Preset Output Voltages (0.8V to 2.5V): The device eliminates the need for external feedback components by offering factory-preset output voltages ranging from 0.8V to 2.5V. This simplifies design, reduces component count, and ensures precise voltage regulation with ±1% initial accuracy.
Ultrasonic Skip Mode for Light Loads: The ultrasonic skip mode optimizes efficiency at light loads down to 1mA, reducing power loss and improving battery life in low-power applications. This feature ensures consistent performance across a wide range of load conditions, enhancing versatility.
