MAX38909

2A High-Performance

nMOS LDO Linear Regulator

General Description

Benefits and Features

The MAX38909 is a fast transient response, high PSRR

nMOS linear regulator that delivers up to 2A of load cur-

rent.

● Delivers Flexible Operating Range

• 0.9V to 5.5V Input Voltage Range

• 2.7V to 20V BIAS Voltage Range

• 0.6V to 5.0V Programmable Output Voltage

• 2A Maximum Output Current

The regulator supports a wide input supply range from

0.9V to 5.5V, and BIAS voltage range from 2.7V to 20V to

provide wider supply options in a variety of applications.

±1% output accuracy is maintained over line, load, and

temperature variations, requiring only 300mV of input-to-

output headroom at full load for a good PSRR. The output

voltage can be adjusted to accommodate customers that

desire to specify a single LDO in the BOM for multiple volt-

age rails.

• 27mV Dropout at 2A Load Current

• 1.6mA Operating BIAS Supply Current

● Reduces Noise and Improves Accuracy

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

Temperature

• 15mV 2A Load Transient Excursion

• 52dB IN PSRR at 10kHz at 300mV Input-to-Output

Headroom

The output voltage on the MAX38909 is programmed to a

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

feedback resistors.

● Enables Ease-of-Use and Robust Protection

• Stable with 10μF (Minimum) Output Capacitance

• Programmable Soft-Start Rate

The LDO is fully protected from damage by internal circuit-

ry that provides programmable inrush current limiting, out-

put overcurrent limiting, reverse-current limiting, and ther-

mal overload protection.

• Overcurrent and Overtemperature Protection

• Output-to-Input Reverse Current Protection

• Power-OK Status Pin

● Reduces Size, Improves Reliability

• 14-Pin (3mm x 3mm) TDFN and 5 x 3 Bump,

0.4mm Pitch WLP Packages

The MAX38909 is offered in 14-pin, 3mm x 3mm TDFN

and 5 x 3 bump, 0.4mm pitch WLP packages.

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

Applications

● FPGAs and DSPs

● Medical, Audio, and Instrumentation

● Server Microcontrollers

● Portable Cameras

● PLCs
