____________________________Fe a t u re s

The MAX603/MAX604 low-dropout, low quiescent cur-

rent, linear regulators supply 5V, 3.3V, or an adjustable

output for currents up to 500mA. They are available in a

1.8W SO package. Typical dropouts are 320mV at 5V

and 500mA, or 240mV at 3.3V and 200mA. Quiescent

currents are 15µA typ and 35µA max. Shutdown turns

off all circuitry and puts the regulator in a 2µA off mode.

A unique protection scheme limits reverse currents

when the input voltage falls below the output. Other fea-

ture s inc lud e foldb a c k c urre nt limiting a nd the rma l

overload protection.

♦ 500mA Output Current, with Foldback Current

Limiting

♦ High-Power (1.8W) 8-Pin SO Package

♦ Dual Mode™ Operation: Fixed or Adjustable

Output from 1.25V to 11V

♦ Large Input Range (2.7V to 11.5V)

♦ Internal 500mA P-Channel Pass Transistor

♦ 15µA Typical Quiescent Current

♦ 2µA (Max) Shutdown Mode

♦ Thermal Overload Protection

♦ Reverse-Current Protection

The output is preset at 3.3V for the MAX604 and 5V for

the MAX603. In addition, both devices employ Dual

Mode™ operation, allowing user-adjustable outputs

from 1.25V to 11V using external resistors. The input

voltage supply range is 2.7V to 11.5V.

______________Ord e rin g In fo rm a t io n

The MAX603/MAX604 fe a ture a 500mA P-c ha nne l

MOSFET p a s s tra ns is tor. This tra ns is tor a llows the

devices to draw less than 35µA over temperature, inde-

p e nd e nt of the outp ut c urre nt. The s up p ly c urre nt

remains low because the P-channel MOSFET pass tran-

sistor draws no base currents (unlike the PNP transis-

tors of conventional bipolar linear regulators). Also,

when the input-to-output voltage differential becomes

small, the internal P-channel MOSFET does not suffer

from excessive base current losses that occur with sat-

urated PNP transistors.
