Product Details

The MAX38913 is a low-noise linear regulator that delivers up to 1A of load current with as low as 4µVRMS of output noise. The MAX38913 can dynamically change its output voltage between two separate levels. The MAX38913 has the pass-through mode which, when enabled, completely bypasses the linear regulator.

This regulator maintains ±1% output accuracy over a wide input voltage range, temperature, and load conditions. The no-load quiescent current in the regulation mode is 1.37mA. During the pass-through mode, unlike the conventional dropout mode of an LDO, the MAX38913 consumes very little quiescent current. The MAX38913 has a 6Ω active discharge feature to quickly discharge output capacitors of up to 300μF.

The MAX38913 has 33 programmable output-voltage settings for both voltage selections.

The MAX38913 is packaged in either a space-saving 12-bump WLP or a full-featured 3mm x 3mm, 14-pin TDFN package. Optional power-OK and power-on-reset pins are available in the 14-pin TDFN version.
