12V, Ultra-Low-I Q , Low-Dropout
Linear Regulators with POK
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.
