The MAX688 evaluation kit (EV kit) provides a regulated 3.3V output voltage while operating on input voltages from 3.5V to 11V. It delivers a 0.5A output current from a 3.5V to 5.75V input, with less than 200mV dropout. Operation with higher input voltages (up to 11V) is possible as long as the maximum power dissipation across the pass transistor is less than 1.25W.
The MAX688 EV kit is a fully assembled and tested surface-mount printed circuit board. The board comes with a 3.3V-output MAX688 IC installed, but can also be used to evaluate the MAX689 (3.0V output), or MAX687 (3.3V output, automatic shutdown). Additional pads are provided on the board's solder side to accommodate the external components used with the MAX687.
