MAX38907/MAX38908

4A, High-Performance

LDO Linear Regulators

General Description

Benefits and Features

The MAX38907/MAX38908 are fast transient response,

high-PSRR nMOS linear regulators that deliver up to 4A

load current.

● 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

• 4A Maximum Output Current

These regulators support a wide input supply range from

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

to provide wider supply options in a variety of applications.

Output accuracy of ±1% 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 a value in the range of 0.6V to

5.0V to accommodate customers that desire to specify a

single LDO in the BOM for multiple voltage rails.

• 51mV Dropout at 4A Load Current

• 1.6mA Operating BIAS Supply Current

● Reduces Noise and Improves Accuracy

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

Temperature

• 28mV, 4A Load-Transient Excursion

• 78dB BIAS PSRR at 10kHz

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

Headroom

The MAX38907 is configurable to one of 27 output volt-

ages using three digital configuration pins. Additionally,

each output voltage selection can be adjusted ±5% for

margining. The output voltage on the MAX38908 can be

adjusted to a value in the range of 0.6V to 5.0V by using

two external feedback resistors. These LDOs are fully pro-

tected from damage by internal circuitry that provides pro-

grammable inrush current limiting, output overcurrent limit-

ing, reverse-current limiting, and thermal overload protec-

tion.

● Enables Ease-of-Use and Robust Protection

• Stable with 10μF (Minimum) Output Capacitance

• Programmable Soft-Start Rate

• Overcurrent and Overtemperature Protection

• Output-to-Input Reverse-Current Protection

• Power-OK Status Pin

● Reduces Size, Improves Reliability

• 14-Pin (3mm x 3mm) TDFN, 20-Pin (5mm x 5mm)

TQFN, and 5 x 3 Bump, 0.4mm Pitch WLP

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

The MAX38907 is offered in a 20-pin, 5mm x 5mm TQFN

package, while the MAX38908 is offered in 5 x 3 bump,

0.4mm pitch WLP and 14-pin, 3mm x 3mm TDFN pack-

ages.
