DESCRIPTION

The TK119xx series are low power, linear regulators with built-in electronic switches. Built-in voltage comparators provide a reset logic ”low” level whenever the input or output voltage falls outside internally preset limits. The internal electronic switch can be controlled by CMOS or TLL levels. The device is in the “off” state when the control pin is biased “high”.
