11µV

Low-Noise, 500mA LDO Linear

MAX38911/MAX38912

RMS

Regulators with Low-Power Mode

General Description

Benefits and Features

The MAX38911/MAX38912 are low-noise, high-PSRR

PMOS linear regulators that deliver up to 500mA load

•

Delivers Wide, Flexible Operating Range

• 1.7V to 5.5V Input Supply Range

• 0.8V to 5.0V Output Voltage Range

• 500mA Maximum Output Current

• 24.3mV Dropout at 500mA Load and 5.0V Input

Voltage

current with only 11µV

of output noise from 10Hz to

RMS

100kHz.

The regulators are fully protected from damage by

internal circuitry that provides programmable inrush

current limiting, output overcurrent limiting, reverse

current limiting, and thermal overload protection.

• 19.2µA No-Load Supply Current in Low-Power

Mode

• 332µA Supply Current in Normal Mode

• <1µA Shutdown Supply Current

The MAX38911 is available in WLP and TDFN packages

and are default factory preprogrammed to an output

voltage of 1.8V. Custom fixed-output voltage levels in

the range of 0.8V to 5.0V in 50mV steps are also

available, see Ordering Information.

•

Reduces Noise and Improves Accuracy

• 11µV

Output Noise, 10Hz to 100kHz

RMS

• 70dB PSRR at 10kHz, 250mA Load Current, and

300mV Input and Output Voltage Separation

• ±1% DC Accuracy over Load, Line,

and Temperature Variations

MAX38912 provides enhanced flexibility with adjustable

output voltage in the range of 0.8V to 5.0V by using two

external feedback resistors.

Enables Ease-of-Use and Robust Protection

• Stable with 2µF (Minimum Effective) Output

Capacitance

• Programmable Soft-Start Rate

• Overcurrent and Overtemperature Protection

• Reverse-Current Protection

The MAX38911ANT is packaged in a 1.42mm x

0.83mm, 3 x 2, 6-bump, 0.4mm pitch WLP, while the

MAX38911ATA and MAX38912ATA are packaged in a

8-pin, 2mm x 2mm TDFN.

Applications

• Power-OK Output

•

Mobile Phones

•

Reduces Size and Improves Reliability

• 1.42mm x 0.83mm, 3 x 2, 6-Bump, 0.4mm Pitch

WLP

• 2mm x 2mm, 8-Pin TDFN Package

• -40°C to +125°C Operating Temperature
