Product Summary

The MAX8902AATA+ is a low-noise linear regulator. It delivers up to 500mA of output current with only 16μVRMS of output noise in a 100kHz bandwidth. The MAX8902AATA+ maintains its output voltage over a wide input range, requiring only 100mV of input-to-output headroom at full load. The applications of the MAX8902AATA+ include Notebook Computers, MP3 and Portable Media Players, Wireless Headphones, GPS Portable Navigation Devices and Smartphones.
