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.

Product Details

The MAX38913A WLP evaluation kit (EV kit) evaluates the MAX38913A in a wafer-level package (WLP). The MAX38913A is a low-noise linear regulator. The EV kit operates over an input range of 1.8V to 5.5V. The EV kit provides an output voltage that is jumper selectable between two separate levels. Each of the two regulated output levels are configured to one of the 33 possible voltages through external select resistors. The MAX38913A EV kit features a pass-through mode that can completely bypass the linear regulator. The EV kit can deliver up to 1A of current.
