The MAX38907/MAX38908/MAX38909 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. ±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 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/MAX38909 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/MAX38909 are offered in 14-pin, 3mm x 3mm TDFN and 5 x 3 bump, 0.4mm pitch WLP packages.
