TK119xx
01S
VOLTAGE REGULATOR WITH RESET OUTPUT
FEATURES
■ Very Low Dropout Voltage
■ Reset Output for Microprocessor
■ Very Low Quiescent Current (No Load)
■ Internal Thermal/Overload Shutdown
■ Low Noise Voltage
■ Input and Output Voltage Sense
■ ± 2.5 % Output Voltage Accuracy
■ CMOS or TTL On/Off Control
■ High Speed On/Off Transient (50 µs typ.)
DESCRIPTION
The TK119xx series are low power, linear regulators with
built-in electronic switches. Built-in voltage comparators
provide a reset logic ”low” level whenever the input or
output voltage falls outside internally preset limits. The
internal electronic switch can be controlled by CMOS or
TLL levels. The device is in the “off” state when the control
pin is biased “high”.
An internal PNP pass-transistor is used in order to achieve
low dropout voltage (typically 200 mV at 50 mA load
current). The device has very low quiescent current
(130 µA) in the “on” mode with no load and 2 mA with 30
mA load. The quiescent current is typically 4 mA at 60 mA
load. The current consumption in the “off” mode is 65 µA.
An internal thermal shutdown circuit limits the junction
temperature to below 150 oC. The load current is internally
monitored and the device will shut down (no load current)
in the presence of a short circuit at the output. The output
noise is very low at 100 dB down from V
external noise bypass capacitor is used. The TK119xx is
available in a miniature SOT-23L surface mount package.
