FEATURES
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.
Very Low Standby Current ( ON, No Load)
Very Low (<200 nA) Current in OFF Mode
Voltage Code
Available on Tape and Reel
Pass Transistor Terminals Available
Low Dropout Voltage
Low Output Noise
Internal Thermal Shutdown
Short Circuit Protection
above 25 C.

APPLICATIONS
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.
