The TLE 4299 supplies a regulated 5 V output voltage with an accuracy of 2% from an
input voltage between 5.5 V and 45 V in the temperature range of Tj = -40 to 150 °C.
The device is capable to supply 150 mA. For protection at high input voltage above 25 V,
the output current is reduced (SOA protection).
An input capacitor is necessary for compensating line influences and to limit steep input
edges. A resistor of approx. 1 ⦠in series with CI, can damp the LC of the input inductivity
and the input capacitor.
The voltage regulator requires for stability an output capacitor CQ of at least 22 µF with
an ESR below 5 â¦.
