MAX77231 Ultra-Low Noise Boost Regulator

MAX77231 Description

MAX77231 EVALUATION KIT AVAILABLE 2.75V to 4.8V Input, 10mA Output, 35µVRMS Ultra-Low Noise Boost Regulator General .
The MAX77231 is optimized for boost applications, requiring very low ripple/noise and small PCB space.

MAX77231 Applications

* requiring very low ripple/noise and small PCB space. Output ripple and noise are suppressed to 35µVRMS (in 1MHz BW) by a PMOS linear post-regulator set 0.5V below the boost regulator output to reject noise while optimizing efficiency. The boost regulator operates using a 1µH/400mA inductor and 2.2µ
