TK115xx

VOLTAGE REGULATOR WITH ON/OFF SWITCH

FEATURES

■ Low Dropout Voltage

■ Pass Transistor Terminals Available

■ Very Low Standby Current ( ON, No Load)

■ Very Low (<200 nA) Current in OFF Mode

■ Low Output Noise

■ Internal Thermal Shutdown

■ Short Circuit Protection

■ Available on Tape and Reel

DESCRIPTION

The TK115xx series devices are low power, linear regu­lators with electronic ON/OFF switches. Both active HIGH
and active LOW control pins are provided.

An internal PNP pass-transistor is used in order to achieve
low dropout voltage (typically 200 mV at 80 mA load
current). A base drive is available at pin 7 for connection
of an external pass transistor should higher current (up to
1 A) or lower dropout voltage is required.

ABSOLUTE MAXIMUM RATINGS

Supply Voltage .........................................................16 V

Load Current .......................................................180 mA

Power Dissipation (Note 1) ................................ 600 mW

Storage Temperature Range ...................-55 to +150 °C

Operating Temperature Range ..................-30 to +80 °C

Lead Soldering Temp. (10 sec.)........................... 260 °C

Junction Temperature .......................................... 150 °C

APPLICATIONS

■ Cordless Telephones

■ Pagers

■ Battery Powered Systems

■ Personal Communications Equipment

■ Portable Instrumentation

■ Radio Control Systems

■ Toys

■ Low Voltage Systems

■ Portable Consumer Equipment

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 TK115xx series is available in plastic surface mount
SOP-8 packages.
