Demonstration circuit 1791A is easy to set up and evalu-
ate the performance of the LTM2887. Refer to Figure 2
for proper measurement equipment setup and follow the
procedure below.
NOTE: When measuring the input or output voltage ripple
or high speed signals, care must be taken to avoid a long
ground lead on the oscilloscope probe.
1. Install JP1 in the ON (default) position.
2. With power off, connect the input power supply to V
and GND on pin header J1.

3. Turn on the power at the input.
NOTE: Make sure that the input voltage does not exceed 6V.
4. Check for the proper output voltages. V
V = 5V on pin header J2.

5. Once the proper output voltages are established, con-
nect signals to J1 and J2 pin headers as appropriate.
The header pin names and locations are detailed on the
demo board silkscreen below the pin headers.
