300mA LDO Linear Regulators with

Internal Microprocessor Reset Circuit

General Description

Features

♦ 3 ✕ 3 UCSP, 6-Pin SOT23, and 8-Pin TDFN

The MAX6469–MAX6484 are low-dropout linear regula-

tors with a fully integrated microprocessor reset circuit.

Each is available with preset output voltages from +1.5V

to +3.3V in 100mV increments and delivers up to 300mA

of load current. These devices consume only 82µA of

supply current. The low supply current, low dropout volt-

age, and integrated reset functionality make these

devices ideal for battery-powered portable equipment.

Packages

♦ Preset +1.5V to +3.3V Output (100mV Increments)

♦ SET Pin for Adjustable Output Voltage

♦ 75μV

LDO Output Voltage Noise

RMS

(MAX6477–MAX6484)

♦ ±2.0% Accuracy Over Temperature

♦ Guaranteed 300mA Output Current

The MAX6469–MAX6484 include a reset output that indi-

cates when the regulator output drops below standard

microprocessor supply tolerances (-7.5% or -12.5% of

nominal output voltage). This eliminates the need for an

external microprocessor supervisor, while ensuring that

supply voltages and clock oscillators have stabilized

before processor activity is enabled. Push-pull and open-

drain active-low reset outputs are available, with reset

timeout periods of 2.5ms, 20ms, 150ms, or 1200ms (min).

♦ Low Dropout Voltage

55mV at 150mA

114mV at 300mA

♦ 82μA Supply Current, 0.1μA Shutdown Current

♦ Input Reverse Current, Thermal and Short-Circuit

Protection

♦ Microprocessor Reset with Four Timeout Options

♦ Push-Pull or Open-Drain RESET

♦ Manual Reset Input

The MAX6469/MAX6470/MAX6473–MAX6478/MAX6481–

MAX6484 also have a shutdown feature that reduces the

supply current to 0.1µA (typ). The MAX6471–MAX6474/

MAX6479–MAX6482 offer a manual reset input to assert a

microprocessor reset while the regulator output is within

specification. The MAX6475/MAX6476/MAX6483/

MAX6484 feature a remote feedback sense pin for use

with an external NPN transistor for higher-current applica-

tions. The MAX6469–MAX6476 are available in 6-pin

SOT23 and 8-pin TDFN packages. The MAX6477–

MAX6484 are available in a 3 × 3 chip-scale package

(UCSP™). All devices are specified for operation from

-40°C to +85°C.

CD/DVD Drives

Note: The first “_ _ are placeholders for the output voltage levels

”

of the devices. Desired output voltages are set by the suffix found

in the Output Voltage Suffix Guide (Table 1). The third “_” is a

placeholder for the reset threshold accuracy. Desired reset

threshold accuracy is set by the suffix found in the Reset

Threshold Accuracy Guide (Table 2). The “_” following the D is a

placeholder for the reset timeout delay time. Desired reset timeout

delay time is set by the suffix found in the Reset Timeout Delay

Guide (Table 3). For example, the MAX6481BL30BD4-T has a

3.0V output voltage, 12.5% reset threshold tolerance, and a

1200ms (min) reset timeout delay. Sample stock is generally avail-

able on standard versions only (Table 4). Standard versions

require a minimum order increment of 2.5k units. Nonstandard

versions must be ordered in 10k-unit increments. Contact factory

for availability.
