BLOCK DIAGRAM

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.

The TK712xx is available in a miniature SOT-25 surface

mount package.
