PRODUCT DESCRIPTION
The SPX116 is a low power, positive voltage regulator. This device is an excellent choice for use in battery-powered applications such
as cordless telephones, radio control systems, and portable computers. The SPX116 features offers very low quiescent currents
(0.4 mA), and very low drop output voltage (50 mV at light load and 300 mV at 100 mA). The SPX116 is a direct replacement for the
TK116. The SPX116 is offered in a 3-pin TO-92 and SOT-89 package.

factor of two over the value needed for the entire
temperature range.
APPLICATION INFORMATION
The SPX116 requires an output capacitor for device stability.
The value required varies greatly depending upon the
application circuit and other factors. The high frequency
characteristics of electrolytic capacitors depend greatly on the
type and also on the manufacturer. Sometimes only bench
testing is the only means to determine the proper capacitor
type and value. Stability can be obtained with a tantalum or
ceramic capacitor value of 4.7 µF or greater.
In most applications the SPX116 is operating at few
milliamps. In these applications the output capacitance can
be further reduced. For example, when the regulator is
running at 10mA output current the output capacitance
value is half compared to the same regulator that is running
at 100mA. The value decreases with higher output voltages,
since the internal loop gain is reduced.
Another critical point of electrolytic characteristics is its
performance over temperature. The SPX116 is designed to
operate starting at -40°C which may not be true in the case of
electrolytic. Higher temperatures generally no problem. The
electrolytic. type in aluminum will freeze around -30°C. This
could cause an oscillation at output of regulator. At a lower
temperature requirement by many applications the capacitor
should maintain its performance. So as a result, for an
application which regulator junction temperature does not
exceed 25°C, the output capacitor can be reduced by the
The worst case occurs at the lower temperature and
maximum operating currents, the entire circuit and the
electrolytic, should be cooled down to the minimum
temperature. The minimum of 0.6 volts required at the input
of regulator above the output to keep the power dissipation
and die heating to its minimum. After the value for the
capacitor has been determined for actual use, the value
should be doubled.
