DESCRIPTION
The TK115xx series devices are low power, linear regulators with electronic ON/OFF switches. Both active HIGH and active LOW control pins are provided.
An internal PNP pass-transistor is used in order to achieve low dropout voltage (typically 200 mV at 80 mA load current). A base drive is available at pin 7 for connection of an external pass transistor should higher current (up to 1 A) or lower dropout voltage is required.

°C |
An internal thermal shutdown circuit limits the junction temperature to below 150 °C. The load current is internally monitored, and the device will shut down in the presence of a short circuit at the output.
The TK115xx series is available in plastic surface mount SOP-8 packages.
