The MAX38913/MAX38914 is a low-noise linear regulator that delivers up to 1A of load current with as low as 4μVRMS of output noise. The MAX38913/MAX38914 can dynamically change its output voltage between two separate levels. The MAX38913/MAX38914 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/MAX38914 consumes very little quiescent current. The MAX38913/MAX38914 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 MAX38914 has pre-programmed output voltage levels of 2.3V and 2V. The MAX38913/MAX38914 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.
