Overview
TK111xxS 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-23-5) s Internal Thermal Shutdown s Short Circuit Protection s Excellent Ripple Rejection (70 dB @ 1 kHz) s Reverse Bias Protection DESCRIPTION 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 The TK111xxS 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 85 mV (typ.
) at ...
