12V, Ultra-Low-I , Low-Dropout

Linear Regulators with POK

General Description

Features

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.

♦ 3.5µA Supply Current at 12V

♦ Reverse Battery Protection

♦ 2.5V to 12V Input Voltage Range

♦

1.5ꢀ ꢁutput Voltage Accuracy

These regulators’ low 3.5µA supply current extends bat-

tery 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 power-OK (POK) com-

parator indicates when the output is out of regulation.

♦ 200mA max ꢁutput Current

♦ 2Ω PMꢁS ꢁutput Device

♦ Short-Circuit and Thermal ꢁverload Protection

♦ PꢁK ꢁutput for ꢁut-of-Regulation Indicator

♦ Fixed 1.8V, 2.5V, 3.3V, and 5V (MAX8881)

Adjustable from 1.25V to 5V (MAX8880)

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.

♦ Tiny 6-Pin SꢁT23 Package

♦ Thin 6-Pin TDFN Package
