Product Details

The MAX1982 evaluation kit (EV kit) provides a regulated 1.2V output voltage while operating on input voltages from 1.25V to 5.5V. It delivers a 0.3A output current from a 1.25V to 2.5V input, with less than 300mV dropout. Operation with higher input voltages (up to 5.5V) is possible as long as the maximum power dissipation across the internal pass transistor is less than 727mW.

The MAX1982 EV kit is a fully assembled and tested surface-mount printed circuit (PC) board. The board is shipped with a fixed 1.2V output MAX1982 IC, and can also be used to evaluate the MAX1983 (adjustable output). Additional pads are provided on the board's component side to accommodate the external components used with the MAX1983.
