ADP1706/ADP1707/ADP1708 is a low dropout CMOS linear regulator with a maximum output current of 1A. It operates within an input voltage range of 2.5V to 5.5V and features low shutdown current, low dropout voltage, high accuracy, and stability. The product offers multiple output voltage options with soft start and tracking functions. It is suitable for applications such as notebook computers, memory components, telecommunications equipment, network equipment, and DSP/FPGA/microprocessors.
The ADP1706, ADP1707, and ADP1708 are CMOS low‑dropout linear regulators that operate from 2.5 V to 5.5 V and deliver up to 1 A of output current. They are intended for notebook computers, memory components, telecommunications, network equipment, DSP/FPGA supplies, and instrumentation systems.
Key features include low shutdown current (<1 pA), low dropout voltage (345 mV at 1 A), soft‑start capability, current‑limit and thermal‑overload protection, and logic‑controlled enable. The devices are offered in 8‑lead SOIC and 8‑lead 3 mm × 3 mm LFCSP packages for compact, thermally efficient designs.
