Functional Description
The TLE4117 is a 3 terminal positive adjustable or fixed voltage regulator. It is capable to supply 800 mA output current. The fixed voltage devices are available for 1.8 V, 2.5V, 3.3 V and 5 V output voltage. The adjustable device requires 2 external resistors to define an output voltage between 1.25 V and 40 V. The TLE4117 is packaged in surface mounted D-Pak package.
The TLE4117 voltage regulator family offers full overload protection, current limitation, thermal protection and save operation area protection (SOA).
An output capacitor of TLE4117 10 F, ESR < 3 is necessary for stability of the regulator loop. The input capacitor is necessary for compensating line influences e.g. to filter glitches. Using a resistor of approx. 1=in series with C , the oscillating circuit consisting of input I nductance and input capacitance can be damped. De-coupling of the adjust pin at variable voltage regulator can improve the ripple rejection ratios.
