TK11320B

TK113xxB VOLTAGE REGULATOR WITH ON/OFF SWITCH FEATURES s High Voltage Precision at ± 2.0% s Active Low On/Off Control s Very Low Dropout Voltage 80 mV at 30 mA s Very Low Noise s Very Small SOT-23L or SOT-89-5 Surface Mount Packages s Internal Thermal Shutdown s Short Circuit Protection DESCRIPTION The TK113xxB is a low dropout linear regulator with a builtin electronic switch. The device is in the ON state when the control pin is pulled to a low level. An external capacitor can be connected to the noise bypass pin to lower the output noise level to 30 µVrms. APPLICATIONS s Battery Powered Systems s Cellular Telephones s Pagers s Personal Communications Equipment s Portable Instrumentation s Portable Consumer Equipment s Radio Control Systems s Toys s Low Voltage Systems The TK113xxB is available in either 6 pin SOT-23L or 5 pin SOT-89-5 surface mount packages. TK113XXB An internal PNP pass transistor is used to achieve a low dropout voltage of 80 mV (typ.) at 30 mA load current....
