DESCRIPTION
TK712xx is a low dropout, linear regulator. Since a PNP
power transistor is used, dropout voltage is very low,
making it possible to maintain stable output voltage even
as the battery decreases. This allows longer battery life.
The TK712xx has a noise bypass pin available for noise
reduction.
