TK116xxU
THREE-TERMINAL VOLTAGE REGULATOR
FEATURES
■ Low Dropout Voltage
■ Very Low Standby Current (No Load)
■ Good Load Regulation
■ Internal Thermal Shutdown
■ Short Circuit Protection
■ 3% Output Voltage Accuracy
■ Customized Versions Are Available
DESCRIPTION
The TK116xxU series devices are low dropout, linear 3terminal 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.
APPLICATIONS
■ Battery Powered Systems
■ Portable Consumer Equipment
■ Cordless Telephones
■ Personal Communications Equipment
■ Portable Instrumentation
■ Radio Control Systems
■ Toys
■ Low Voltage Systems

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.
