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 built-
in 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 (typ.) at 30 mA load current. The
TK111xxM has a very low quiescent current of 140 µA
(typ.) at no load . The standby current is 100 nA maximum.
The internal thermal shutdown circuitry limits the junction
temperature to below 150 °C. The load current is internally
monitored and the device will shut down in the presence of
a short circuit or overcurrent condition at the output.
