T he 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

thermal-overload protection.

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.

For low-dropout linear regulators with output currents up

to 500mA, refer to the MAX603/MAX604 data sheet.
