Application Information
Figure 3
In the TLE 4264-2 the output voltage is divided and compared to an internal reference of
2.5 V typical. The regulation loop controls the output to achieve an output voltage of 5 V
with an accuracy of 3% at an input voltage range of 5.5 V <

TLE 4264-2 output requires an output capacitor
permissible ESR of 4 . Tantalum as well as multi layer ceramic capacitors are suitable.
At the input of the regulator an input capacitor is necessary for compensating line
influences (100 nF ceramic capacitor recommended). A resistor of approx. 1

capacitor.
In the application circuit shown in
470 F is added in order to buffer supply line influences. This capacitor is recommended,
if the device is sourced via long supply lines of several meters.
The TLE 4264-2 can supply up to 150 mA. However for protection for high input voltage
above 25 V, the output current is reduced (SOA protection).
