DESCRIPTION
The TK116xxU series devices are low dropout, linear 3-terminal regulators.
An internal PNP pass-transistor is used in order to achieve low dropout voltage (typically 160 mV at 80 mA load current).
The regulated output voltages of 3, 3.3, 5 and 9 V are available. The device has very low (400 µA) quiescent
current with no load and 2 mA with 60 mA load.
An internal thermal shutdown circuit limits the junction temperature to below 150 °C. The load current is internally monitored and the device will shut down in the presence of a short circuit at the output.
