产品概述

The MAX8880/MAX8881 are ultra-low supply current,low-dropout linear regulators, capable of delivering upto 200mA. They are designed for battery-poweredapplications where reverse battery protection and longbattery life are critical.

These regulators' low 3.5µA supply current extends batterylife in applications with long standby periods. UnlikePNP-based designs, a 2Ω PMOS device maintains ultra-lowsupply current throughout the entire operating rangeand in dropout. The parts are internally protected fromoutput short circuits, reverse battery connection, andthermal overload. An internal power-OK (POK) comparatorindicates when the output is out of regulation.

The MAX8880 output is adjustable from 1.25V to 5Vusing an external resistor-divider. The MAX8881 providesonly factory-preset output voltages of 1.8V, 2.5V,3.3V, or 5V (see Ordering Information in the full data sheet). The devices are available in 6-pin SOT23 and 6-pin TDFN packages.
