MAX1982 Evaluation Kit
General Description
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 dissi-
pation 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 out-
put). Additional pads are provided on the board鈥檚 com-
ponent side to accommodate the external components
used with the MAX1983.
