Product Details

The MAX38902 evaluation kit (EV kit) evaluates the MAX38902A/B/C/D IC family of low noise linear regulators. The MAX38902 EV kit features two independent circuits to evaluate two different IC packages of the MAX38902A/B/C/D family. Both circuits on the EV kit operate over an input range of 1.7V to 5.5V, and provide any output voltage range of 0.6V to 5.3V. The TDFN circuit evaluates the MAX38902A/B, while the wafer-level package (WLP) circuit evaluates the MAX38902C/D. Each circuit output on the EV kit delivers up to 500mA of current.

The EV kit comes with the MAX38902A-ATA+ and the MAX38902C-ANT+ installed.
