The MAX882/MAX883/MAX884 linear regulators maxi-  
mize battery life by combining ultra-low supply currents  
and low dropout voltages. They feature 200mA output  
current capability at up to +125°C junction temperature  
and come in a 1.5W SOIC package. The 1.5W package  
(c omp a re d to 0.47W for s ta nd a rd SOIC p a c ka g e s )  
allows a wider operating range for the input voltage and  
output current. The MAX882/MAX883/MAX884 use a P-  
channel MOSFET pass transistor to maintain a low 11µA  
(15µA ma x) s up p ly c urre nt from no-loa d to the full  
200mA output. Unlike earlier bipolar regulators, there are  
no PNP base current losses that increase with output  
current. And, in dropout, the MOSFET does not suffer  
from excessive base currents that occur when PNP tran-  
sistors go into saturation. Typical dropout voltages are  
220mV at 5V and 200mA, or 320mV at 3.3V and 200mA.

The MAX882 features a 7µA standby mode that disables  
the output but keeps the reference, low-battery compara-  
tor, and biasing circuitry alive. The MAX883/MAX884 fea-  
ture a shutdown (OFF) mode that turns off all circuitry,

devices include a low-battery-detection comparator, fold-  
back current limiting, reverse-current protection, and  
thermal overload protection.

______________Ord e rin g In fo rm a t io n  
The output is preset at 3.3V for the MAX882/MAX884  
and 5V for the MAX883. In addition, all devices employ  
Dual Mode™ operation, allowing user-adjustable outputs  
from 1.25V to 11V using external resistors. The input volt-  
age supply range is 2.7V to 11.5V.
