MAX38904A/B/C/D

1.7V to 5.5V , 2A Low-Noise LDO Linear

Regulators in TDFN and WLP

General Description

Benefits and Features

The MAX38904 is a 1.7V–5.5V V , low-noise linear reg-

ulator that delivers up to 2A of output current with only

● Delivers Flexible Operating Range

• 1.7V to 5.5V Input Voltage Range

• 0.6V to 5.0V Programmable Output Voltage

• 2A Maximum Output Current

5.1μV

of output noise from 10Hz to 100kHz. The reg-

RMS

ulator maintains ±1% output accuracy over a wide in-

put voltage range, requiring only 100mV of input-to-output

headroom at full load. The 1.3mA no-load supply current is

independent of dropout voltage. The MAX38904A/B/C/D

have a 70Ω active discharge feature to quickly discharge

output capacitors.

• 100mV Maximum Dropout at 2A Load

• < 1.5μA Shutdown Supply Current

● Reduces Noise and Improves Accuracy

• ±1% DC Accuracy Over Load, Line, and

Temperature

The output voltage on MAX38904B can be adjusted to a

value in the range of 0.6V to 5.0V by using two external

resistors. The MAX38904B also includes an active-high

POK signal for trouble-free load startup.

• 5.1μV

Output Noise, 10Hz to 100kHz

RMS

• 1.3mA Quiescent Supply Current

• > 70dB PSRR at 10kHz

● Enables Ease-of-Use and Robust Protection

• Active Discharge of 70Ω at OUT

The MAX38904A has nine pin-selectable output voltages

1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 4.0V, and 5V.

• Stable with 8μF (Min) Output Capacitance

• Programmable Soft-Start Rate

• Overcurrent and Overtemperature Protection

• Output-to-Input Reverse Current Protection

• Power-OK Status Pin

The wafer-level package (WLP) versions of the

MAX38904 are available as C and D variants. The

MAX38904C uses external feedback resistors for adjust-

ing the output voltage, while the MAX38904D has factory

preset output voltages over the range of 0.7V to 5.0V in

50mV steps.

● Reduces Size, Improves Reliability

• 3mm x 3mm 14-pin TDFN Package and 2.2mm x

1.37mm, 5 x 3 Bump, 0.4mm Pitch WLP

• -40ºC to 125ºC Operating Temperature

All versions include a programmable output soft-start rate,

output overcurrent, and thermal overload protection.

The MAX38904A/B are offered in a 3mm x 3mm, 14-pin

TDFN package, while the MAX38904C/D are available in

5 x 3 bump, 2.2mm x 1.37mm WLP, 0.4mm pitch.

Applications

● Communication Systems, Test Equipment, Medical

Equipment

● High-End Audio Systems

● High-Resolution Data Acquisition Systems
