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 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 presenc...
