DESCRIPTION
The TK113xxB is a low dropout linear regulator with a builtin electronic switch. 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 mV (typ.) at 30 mA load current. The TK113xxB has a very low quiescent current of 170 µA at no load and 1 mA with a 30 mA load. The standby current is typically 100 nA. 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 TK113xxB is available in either 6 pin SOT-23L or 5 pin SOT-89-5 surface mount packages.

When mounted as recommended. Derate at 4.8 mW/°C for SOT-23L and 6.4 mW/°C for SOT-89-5 packages when ambient temperatures are over 25 °C. Note 2: For Line Regulation V O > 5.6 V, Typ and Max values are 15 and 40 mV. Note 3: Refer to Definition of Terms. Note 4: Ripple Rejection and noise voltage are affected by the value and characteristics of the capacitor used. Note 5: Output noise voltage can be reduced by connecting a capacitor to a noise pass terminal. Gen. Note: Parameters with min. or max. values are 100% tested at TA = 25 °C.
