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.
