Description
ADJUSTABLE LOW DROPOUT REGULATOR

TK119xx
Note: V
may overlap.
The figure below illustrates the TK119xx. The TK119xx
utilizes the same reference voltage for both the voltage
regulator and the voltage detector functions. As a result,
the detector voltage is always constant (V
from the output voltage. With this approach, the two
ranges do not overlap.

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.
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.
