DESCRIPTION
The TK114xx is a low power, linear
regulator with a builtin electronic switch.
The internal electronic switch can be controlled by an external pull-up resistor and an open drain or open collector
transistor.
The device is in the OFF state when the control pin is biased from VIN through the pull-up resistor.
An internal
PNP pass-
transistor is used in order to achieve low dropout voltage (typically 200 mV at 5...
