1 / 26 page  February, 1995 TOKO, Inc. TK115xx Page 1 10-15-94 APPLICATIONS s Cordless Telephones s Pagers s Battery Powered Systems s Personal Communications Equipment s Portable Instrumentation s Radio Control Systems s Toys s Low Voltage Systems s Portable Consumer Equipment FEATURES s Low Dropout Voltage s Pass Transistor Terminals Available s Very Low Standby Current ( ON, No Load) s Very Low (<200 nA) Current in OFF Mode s Low Output Noise s Internal Thermal Shutdown s Short Circuit Protection s Available on Tape and Reel DESCRIPTION The TK115xx series devices are low power, linear regu- lators 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.

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.
