• Manufacturer Part Number: tle4299
• Description: Low-drop Fixed Voltage Regulator
• Manufacturer: Infineon Technologies Corporation

Figure 7
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
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
and the input capacitor.
The voltage regulator requires for stability an output capacitor
an 0.4
