FEATURES
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 A) 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.
The TK116xxU is available in the SOT-89 surface mount
package.
