MAX38902EATA+T

The MAX38902E is low-noise linear regulator that delivers up to 500mA of output current with only 14uVRMS of output noise from 10Hz to 100kHz. This regulator maintains ±1% output accuracy over a wide input voltage range, requiring only 100mV of input-to-output headroom at full load. The 600uA no-load supply current is independent of dropout voltage. The MAX38902E, low noise linear regulator delivers up to 500mA of output current, with only 14uVRMS of output noise in a 10Hz to 100kHz bandwidth. This regulator maintains its output voltage over a wide input range, requiring only 100mV of input-to-output headroom at full load. The MAX38902E maintains a low 600uA typical supply current, independent of the load current and drop-out voltage. The regulator control circuitry includes a programmable soft-start circuit, short-circuit, reverse input current, and thermal overload protection. Other features include an enable input and power-okay (POK) output.
