MAXIM INTEGRATED / ANALOG DEVICES MAX603CPA Linear Regulator

The MAX603/MAX604 are low-dropout, low quiescent current linear regulators designed for battery-powered applications. They offer an adjustable output from 1.25V to 11V or fixed 5V and 3.3V, supporting load currents up to 500mA. Featuring an internal P-channel MOSFET pass transistor, foldback current limiting, reverse-current protection, thermal overload protection, and dual-mode operation for fixed or adjustable voltage. Their small SO package and low quiescent current make them ideal for portable devices like pagers, cellular phones, and solar-powered instruments, ensuring efficiency and reliable voltage regulation in limited space.
