500mA Low-Dropout

Linear Regulator in SOT23

MAX18

General Description

Features

The MAX1818 low-dropout linear regulator operates

from a +2.5V to +5.5V supply and delivers a guaran-

teed 500mA load current with low 120mV dropout. The

high-accuracy ( 1ꢀ% output voltage is preset at an

internally trimmed voltage (see Selector Guide% or can

be adjusted from 1.25V to 5.0V with an external resis-

tive divider.

♦ Guaranteed 500mA Output Current

♦ Low 120mV Dropout at 500mA

♦

1% Output Voltage Accuracy

Preset at 1.5V, 1.8V, 2.0V, 2.5V, 3.3V, 5V

Adjustable from 1.25V to 5.0V

♦ Power OK Output

An internal PMOS pass transistor allows the low 125µA

supply current to remain independent of load, making

this device ideal for portable battery-operated equip-

ment such as personal digital assistants (PDAs%, cellu-

lar phones, cordless phones, base stations, and

notebook computers.

Other features include an active-low open-drain reset

output that indicates when the output is out of regula-

tion, a 0.1µA shutdown, short-circuit protection, and

thermal shutdown protection. The device is available in

a miniature 800mW 6-pin SOT23 package.

♦ Low 125µA Ground Current

♦ 0.1µA Shutdown Current

♦ Thermal Overload Protection

♦ Output Current Limit

♦ Tiny 800mW 6-Pin SOT23 Package
