Functional Description

The TLE 4117 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, 2.5 V,

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 TLE 4117 is packaged in surface

mounted D-Pak package.

The TLE 4117 voltage regulator family offers full overload protection, current limitation,

thermal protection and save operation area protection (SOA).

An output capacitor of 10

µF, ESR < 3 Ω 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

Ω=in series with C

inductance and input capacitance can be damped. De-coupling of the adjust pin at

variable voltage regulator can improve the ripple rejection ratios.
