DESCRIPTION
The TK114xx is a low power, linear regulator with a builtin electronic switch. The internal electronic switch can be
controlled by an external pull-up resistor and an open drain
or open collector transistor. The device is in the OFF state
when the control pin is biased from VIN through the pull-up
resistor.
TK114xxM
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 (500
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. An
internal thermal shutdown circuit limits the junction temperature to below 150 °C. 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 device
is available in a small SOT-23L surface mount package.

Handling Molded Resin Packages
All plastic molded packages absorb some moisture from
the air. If moisture absorption occurs prior to soldering the
device into the printed circuit board, increased separation
of the lead from the plastic molding may occur, degrading
the moisture barrier characteristics of the device.
This property of plastic molding compounds should not be
overlooked, particularly in the case of very small packages,
where the plastic is very thin.
Page 22
Application Hints
Maximize copper foil area connecting to all IC pins for
optimum performance. Place input and output bypass
capacitors close to the GND pin. For best transient behavior and lowest output impedance, use as large a capacitor
value as possible. The temperature coefficient of the capacitance and Equivalent Series Resistance (ESR) should
be taken into account. These parameters can influence
power supply noise and ripple rejection. In extreme cases,
oscillation may occur. In order to maintain stability, the
output bypass capacitor value should be minimum 2.2 µF
for a Tantalum electrolytic or 4.7 µF for an Aluminum
electrolytic.
In order to preserve the original moisture barrier properties
of the package, devices are stored and shipped in moisture
proof bags, filled with dry air. The bags should not be
opened or damaged prior to the actual use of the devices.
If this is unavoidable, the devices should be stored in a low
relative humidity environment (40 to 65%) or in an enclosed
environment with desiccant.
