10 Power Supply Recommendations

The low supply current and supply range of 2.7 V to 5.5 V allow the device to easily be powered from many

sources.

Power supply bypassing is optional and is mainly dependent on the noise on the power supply used. In noisy

systems it may be necessary to add bypass capacitors to lower the noise that is coupled to the output of the

LMT87.

11 Layout

11.1 Layout Guidelines

The LMT87 is extremely simple to layout. If a power supply bypass capacitor is used, it should be connected as

shown in the Layout Example.
