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 2
PMOS device main-
tains 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) comparator 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
). Both devices
are available in miniature 6-pin SOT23 packages.
