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_j = – 40 to 150 °C, in an output
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 Ω in series with C_I, can damp the LC of the input inductivity and the input
capacitor.
The voltage regulator requires for stability an output capacitor C_Q of at least 22 µF with an 0.4Ω
< ESR < 3.7Ω for the whole load- and temperature range. For more detailed information, refer to
the characteristical curves.
