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 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.

APPLICATION INFORMATION

The SPX116 requires an output capacitor for

device stability. The capacitor value required

varies greatly depending upon the application

circuit and other factors. The high frequency

characteristicsofelectrolyticcapacitorsdepend

greatly on the type and also on the manufac-

turer.Sometimesbenchtestingistheonlymeans

todeterminethepropercapacitortypeandvalue.

Stability can be obtained with a tantalum or

ceramic capacitor value of 4.7 µF or greater.

the output capacitor can be reduced by a factor

of two over the value needed for the entire

temperature range.

In most applications the SPX116 is operating at

a few milliamps. In these applications, the out-

put 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 character-

istics is the performance over temperature. The

SPX116 is designed to operate starting at -40°C

which may not be true in the case of electrolytic

components. Higher temperatures generally

present no problems for electrolytics. The

electrolytic type in aluminum will freeze at

about -30°C. This could cause an oscillation at

the output of the regulator. At a lower tempera-

ture requirement by many applications the ca-

pacitor should maintain its performance. So as

a result, for an application in which the regula-

tor junction temperature does not exceed 25°C,

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 mini-

mum of 0.6 volts is required at the input of the

regulator above the output to keep the power

dissipation and die heating to its minimum.

After the value for the capacitor has been deter-

minedforactualuse,thevalueshouldbe doubled.
