DESCRIPTION
The TK116xxU series devices are low dropout, linear 3-
terminal regulators.
An internal PNP pass-transistor is used in order to achieve
low dropout voltage (typically 160 mV at 80 mA load
current).
The regulated output voltages of 3, 3.3, 5 and 9 V are
available. The device has very low (400 µA) quiescent
current with no load and 2 mA with 60 mA load.
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 TK116xxU is available in the SOT-89 surface mount
package.

DEFINITION AND EXPLANATION OF TECHNICAL TERMS (CONT.)
thermal equilibrium is reached. The range of usable currents
can also be found from the graph below:

Procedure:
1) Find PD
2) PD1 is taken to be PD x (~ 0.8 - 0.9)
3) Plot PD1 against 25 °C.
4) Connect PD1 to the point corresponding to the 150 °C
with a straight line.
5) In design, take a vertical line from the maximum operating
temperature (e.g., 75 °C.) to the derating curve.
6) Read off the value of PD against the point at which the
The maximum operating current is:
IOUT = (DPD / (VIN(MAX) - VOUT)
