DESCRIPTION  
TheTK111xxSisalowdropoutlinearregulatorwithabuilt-  
in electronic switch. The internal switch can be controlled  
byTTLorCMOSlogiclevels. Thedeviceisintheonstate  
when the control pin is pulled to a logic high level. An  
external capacitor can be connected to the noise bypass  
pin to lower the output noise level to 30 µVrms.

An internal PNP pass transistor is used to achieve a low  
dropout voltage of 85 mV (typ.) at 30 mA load current. The  
TK111xxS has a very low quiescent current of 140 µA  
(typ.) at no load . The standby current is 100 nA maximum.  
The internal thermal shut down circuitry 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 or overcurrent condition at the output.
