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
