GENERAL DESCRIPTION
The MAX8880/MAX8881 are ultra-low supply current, low-dropout linear regulators, capable of delivering up to 200mA. They are designed for battery-powered applications where reverse battery protection and long battery life are critical. These regulators’ low 3.5µA supply current extends battery life in applications with long standby periods. Unlike PNP-based designs, a 2Ω PMOS device maintains ultra-low supply current throughout the entire operating range and in dropout. The parts are internally protected from output short circuits, reverse battery connection, and thermal overload. An internal powerOK (POK) comparator indicates when the output is out of regulation. The MAX8880 output is adjustable from 1.25V to 5V using an external resistor-divider. o 3.5µA Supply Current at 12V o Reverse Battery Protection o 2.5V to 12V Input Voltage Range o ±1.5% Output Voltage Accuracy o 200mA max Output Current o 2Ω PMOS Output Device o Short-Circuit and Thermal Overload Protecti...
