Overview
TK112xxA VOLTAGE REGULATOR WITH ON/OFF SWITCH FEATURES s High Voltage Precision at ± 2.
4% s Active High 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 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 DESCRIPTION The TK112xxA is a low dropout linear regulator with a builtin electronic switch.
The internal switch can be controlled by TTL or CMOS logic levels.
The device is in the ON state when the control pin is pulled to a logic high level.
An external capacitor can be connected to the noise bypass pin to lower the output noise level to 30 µVrms.
An internal PNP pass transistor is used to achieve a low dropout voltage of 70 mV (typ.
) at 30 mA load current.
The TK112xxA has a very l...
