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 bat- tery life in applications with long standby periods. Unlike PNP-based designs, a 2 Ω 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 power-OK (POK) com- parator indicates when the output is out of regulation. The MAX8880 output is adjustable from 1.25V to 5V using an external resistor-divider. The MAX8881 pro- vides only factory-preset output voltages of 1.8V, 2.5V, 3.3V, or 5V (see Ordering Information). The devices are available in 6-pin SOT23 and 6-pin TDFN packages.
