DESCRIPTION
The TK114xx is a low power, linear regulator with a built-
in 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 V
IN
through the pull-up
resistor.
An internal PNP pass-transistor is used in order to achieve
low dropout voltage (typically 200 mV at 50 mA load
current). The device has very low quiescent current (500
μ
A) in the ON mode with no load and 2 mA with 30 mA load.
The quiescent current is typically 4 mA at 60 mA load. An
internal thermal shutdown circuit limits the junction tem-
perature to below 150
°
C. The load current is internally
monitored and the device will shut down (no load current)
in the presence of a short circuit at the output. The device
is available in a small SOT-23L surface mount package.
