Low-Input-Voltage, 500mA LDO Regulator

RESET

with

in SOT and TDFN

General Description

Features

♦ Low 1.62V Minimum Input Voltage

♦ Guaranteed 500mA Output Current

The MAX1589 low-dropout linear regulator operates

from a +1.62V to +3.6V supply and delivers a guaran-

teed 500mA continuous load current with a low 175mV

dropout. The high-accuracy ( 0.5%) output voltage is

preset to internally trimmed voltages from +0.75V to

+3.0V. An active-low, open-drain reset output remains

asserted for at least 70ms after the output voltage reach-

es regulation. This device is offered in 6-pin thin SOT23

and 6-pin 3mm x 3mm thin DFN packages.

♦

0.5ꢀ Initial Accuracy

♦ Low 175mV Dropout at 500mA Load

♦ 70ms RESET Output Flag

♦ Supply Current Independent of Load and Dropout

Voltage

♦ Logic-Controlled Shutdown

♦ Thermal-Overload and Short-Circuit Protection

♦ Preset Output Voltages (0.75V, 1.0V, 1.2V, 1.3V,

An internal PMOS pass transistor maintains low supply

current, independent of load and dropout voltage, making

the MAX1589 ideal for portable battery-powered equip-

ment such as personal digital assistants (PDAs), digital

still cameras, cell phones, cordless phones, and note-

book computers. Other features include logic-controlled

shutdown, short-circuit protection, and thermal-

overload protection.

1.5V, 1.8V, 2.5V, and 3.0V)

♦ Tiny 6-Pin Thin SOT23 Package (<1.1mm High)

♦ Thin 6-Pin TDFN Package (<0.8mm High)
