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.

BLOCK DIAGRAM
TK115xxM
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.

For small changes in output voltage use R1 to increase
the output voltage or R2 to decrese the output voltage.
The graph at right shows the approximate resistance
values. The initial output voltage is indicated on the
graph. (3 V = TK11530 etc.)

For large adjustment range use a 50 K potentiometer.
This method gives good results when a voltage lower

TYPICAL APPLICATIONS (CONT.)
APPLICATION HINTS
Maximize copper foil area connecting to all IC pins for
optimum performance. Place input and output bypass
capacitors close to the GND pin. For best transient
behavior and lowest output impedance, use as large a
capacitor value as possible. The temperature coefficient
of the capacitance and Equivalent Series Resistance
(ESR) should be taken into account. These parameters
can influence power supply noise and ripple rejection. In
extreme cases, oscillation may occur. In order to maintain
stability, the output bypass capacitor value should be
minimum 1 µF for Tantalum electrolytic or 4.7 µF for
Aluminum electrolytic at T
