DESCRIPTION
TK713xx is a low dropout, linear regulator with a built-in
electronic switch. Since a PNP power transistor is used,
dropout voltage is very low, making it possible to maintain
a stable output voltage even as the battery voltage
decreases. This allows longer battery life. The TK713xx
has a control pin to turn the output on or off. The input
current is 10
µA
when the output is off.
