High-Current, Low-Voltage Linear Regulator

with Power-Limited, External MOSFET

General Description

Features

The MAX8704 high-current linear regulator uses an

external n-channel MOSFET to generate low-voltage

supplies for notebook computers. This linear regulator

delivers an output voltage as low as 0.5V from an input

voltage as low as 1.0V. Normally, this low input require-

ment would make the design of such a regulator very dif-

ficult. In this application, the 5V bias supply that is

always available in the system powers the MAX8704 dri-

ver and control circuitry.

♦ Low-Cost, High-Current Linear Regulator

♦ External MOSFET Protection

MOSFET Power Limit

50mV (typ) Current Limit

Thermal Limit

♦ 1.0V to 5.5V Input Supply Voltage

♦ 1.2V or 1.5V Preset, or Adjustable Output Voltage

The MAX8704 includes a fixed current limit and an

adjustable power limit to protect the external MOSFET

from overheating. Additionally, the MAX8704 includes

an internal thermal limit to prevent damage to the con-

troller and provide remote thermal protection for the

external MOSFET.

♦ Power-Good (PGOOD) Open-Drain Output with

3ms Startup Delay

♦ Programmable Soft-Start

♦ Shutdown with Output Discharge

The MAX8704 features an adjustable soft-start function

and generates a delayed power-good (PGOOD) signal

that signals when the linear regulator is in regulation.

The MAX8704 is available in a 10-pin µMAX^®package.
