Application Diagram with Inhibit Function TLE4299 GMV33

The TLE 4299 supplies a regulated 3.3 V output voltage with an accuracy of 2% for an input

voltage between 4.4 V and 45 V in the temperature range of

T

current range of 1 mA to 100 mA.

The device is capable to supply 150 mA with an accuracy of 3%. 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

capacitor.

The voltage regulator requires for stability an output capacitor

< ESR < 3.7

Ω for the whole load- and temperature range. For more detailed information, refer to
