5V/3.3V or Adjustable, Low-Dropout,
Low I Q , 200mA Linear Regulators
General Description
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
(compared to 0.47W for standard SOIC packages)
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 max) supply current from no-load to the full
200mA output. Unlike earlier bipolar regulators, there are
no PNP base current losses that increase with output
current. In dropout, the MOSFET does not suffer from
excessive base currents that occur when PNP transistors
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,
reducing supply current to less than 1μA. All three
devices include a low-battery-detection comparator, fold-
back current limiting, reverse-current protection, and

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.
