Analog Devices / Maxim Integrated MAX38913/MAX38914 4µVRMS Ultra-Low-Noise 1A LDOs
Analog Devices MAX38913/MAX38914 4µVRMS Ultra-Low-Noise 1A LDO enables a dynamic change to its output voltage between two separate levels. ADI MAX38913/MAX38914 has the pass-through mode, which, when active, completely bypasses the linear regulator.
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 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.
