The TK11250 is a low power, linear regulator with a builTInelectronic switch. The internal electronic switch can becontrolled by TTL or CMOS logic levels. The device is inthe ON state when the control pin is pulled to a high logiclevel. A pin for a bypass capacitor is provided, whichconnects to the internal circuitry, to lower the overall outputnoise level.An internal PNP pass-transistor is used in order to achievelow dropout voltage (typically 100 mV at 30 mA loadcurrent). The device has very low quiescent current (180mA) in the ON mode with no load and 1 mA with 30 mA load.The quiescent current is typically 2.5 mA at 60 mA load.When the device is in standby mode (VCONT = 0), thequiescent current is typically 100 nA. An internal thermalshutdown circuit limits the juncTIon temperature to below150 °C. The load current is internally monitored and thedevice will shut down in the presence of a short circuit at theoutput.
