MAX38903A/MAX38903B/

MAX38903C/MAX38903D

1.7V—5.5V , 1A Low Noise LDO Linear

Regulators in TDFN and WLP

General Description

The MAX38903A/B/C/D are a family of low-noise linear

regulators that deliver up to 1A of output current with only

Beneﬁts and Features

● Delivers Flexible Operating Range

• 1.7V to 5.5V Input Voltage Range

• 0.6V to 5.0V Programmable Output Voltage

• 1A Maximum Output Current

7µV

of output noise from 10Hz to 100kHz.

RMS

These regulators maintain ±1% output accuracy over a

wide input voltage range, requiring only 100mV of input-

to-output headroom at full load. The 1200µA no-load

supply current is independent of dropout voltage.

• 100mV Maximum Dropout at 1A Load

• < 1µA Shutdown Supply Current

● Reduces Noise and Improves Accuracy

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

The MAX38903A has nine pin-selectable output voltages

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

MAX38903B/C output voltage can be adjusted to a value

in the range of 0.6V to 5.0V using two external resistors.

The MAX38903B also includes an active-high POK signal

for trouble-free load startup.

• 7µV

Output Noise, 10Hz to 100kHz

RMS

• 1200µA Operating Supply Current

• 70dB PSRR at 10kHz

● Enables Ease-of-Use and Robust Protection

• Stable with 4μF(min) Output Capacitance

• Programmable Soft-Start Rate

The MAX38903D has factory-preset output voltages

over the range of 0.7V to 5V in 50mV steps. All versions

include a programmable output soft-start rate, output

over-current and thermal overload protection.

• Overcurrent and Overtemperature Protection

• Output-to-Input Reverse Current Protection

• Power-OK Output

● Reduces Size, Improves Reliability

The MAX38903A/B are offered in a 10-pin, 3mm x 3mm

TDFN package, while the MAX38903C/D are offered

in a 9-bump, 0.4mm pitch, 1.4mm x 1.4mm wafer-level

package (WLP).

• 3mm x 3mm, 10-pin TDFN Package and

1.4mm x 1.4mm, 3 x 3 Bump, 0.4mm Pitch WLP

• -40°C to 125°C Operating Temperature

Ordering Information appears at end of data sheet.

Applications

● Communication Systems, Test Equipment, Medical

Equipment

● High-End Audio Systems

● High-Resolution Data Acquisition Systems
