MAX603/MAX604

5V/3.3V or Adjustable, Low-Dropout,

Low I , 500mA Linear Regulators

General Description

Features

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

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 features include foldback current

limiting and thermal 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

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.

● Thermal Overload Protection

● Reverse-Current Protection

Applications

The MAX603/MAX604 feature a 500mA P-channel

MOSFET pass transistor. This transistor allows the devices

to draw less than 35μA over temperature, independent

of the output current. The supply current remains low

because the P-channel MOSFET pass transistor draws

no base currents (unlike the PNP transistors 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 saturated PNP transistors.

● 5V and 3.3V Regulators

● 1.25V to 11V Adjustable Regulators

● Battery-Powered Devices

● Pagers and Cellular Phones

● Portable Instruments

● Solar-Powered Instruments
