TK11144M

TK111xxM VOLTAGE REGULATOR WITH ON/OFF SWITCH FEATURES s High Voltage Precision at ± 2.0% or ± 60 mV s Active High On/Off Control s Very Low Dropout Voltage (85 mV at 30 mA) s Very Low Noise s Miniature Package (SOT-23L-6) s Internal Thermal Shutdown s Short Circuit Protection s Excellent Ripple Rejection (70 dB @ 1 kHz) s Reverse Bias Protection DESCRIPTION The TK111xxM 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. 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 TK111xxM An internal PNP pass transistor is used to achieve a low dropout voltage of 85 mV (...
