What is the LND-7900
The LND-7900 is Linear Dimensions’ version of the popular LND-7900 series negative voltage
low dropout regulator family. These devices offer voltage regulation at extremely low cost. The
devices are particularly useful in applications such as wall adaptors, toys, or wall plugged devices
which aren’t power critical but which require power regulation. These devices are available in a
variety of voltage varieties including: -6, -8, -9, -12, -15, -18, -24V.
How does it work
To use the device simply connect the power and GND pins, the centre pin will represent the
regulated output voltage.
How Do I get samples
The LND-7900 are available in standard TO-92 plastic packages in both sample and volume.
When ordering, replace the 00 with the appropriate voltage level, eg. LND-7906 would result in a
6V, TO-92, plastic package part.
