Key Featrues
180° Phased Dual Controllers: This feature reduces the required input capacitance and minimizes power supply-induced noise by operating the two controller output stages out of phase. This enhances efficiency and stability in high-performance applications like battery-operated devices and DC power distribution systems.
OPTI-LOOP® Compensation: By minimizing the output capacitance (COUT), this feature improves transient response and reduces the overall size and cost of the system. It is particularly beneficial in portable instruments and compact devices where space is a constraint.
Wide VIN Range (4.5V to 28V): The regulator's ability to operate over a wide input voltage range makes it versatile for use in diverse applications, from notebook computers to battery chargers, ensuring consistent performance across varying power sources.
Very Low Dropout Operation (99% Duty Cycle): This feature maximizes efficiency by allowing the regulator to operate with minimal voltage drop, even at high loads. It is ideal for battery-powered devices, extending battery life and improving energy utilization.
Adjustable Soft-Start Current Ramping: This feature prevents inrush current during startup, protecting the system and connected components from damage. It is particularly useful in applications like battery chargers and portable instruments, where controlled startup is critical.
