The MAX38907/MAX38908 are fast transient response,
high-PSRR nMOS linear regulators that deliver up to 4A
load 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.
The MAX38907 is configurable to one of 27 output voltages
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 protected
from damage by internal circuitry that provides programmable
inrush current limiting, output overcurrent limiting,
reverse-current limiting, and thermal overload protection.
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 packages.
