The device is in the ON state when the control pin is pulled to a low 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 80 m V (typ.) at 30 m A load current. The TK113xx B has a very low quiescent current of 170 µA at no load and 1 m A with a 30 m A load. The standby current is typically 100 n A. The internal thermal shutdown circuitry limits the junction temperature to below 150 °C. The load current is internally monitored and the device will shutdown in the presence of a short circuit or overcurrent condition at the output. The TK113xx B is available in either 6 pin SOT-23L or 5 pin SOT-89-5 surface mount packages.
