DESCRIPTION
The TK115xx series devices are low power, linear regu-
lators 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.
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.
