Circuit Description and Application Information
In the TLE 4266-2 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 2% at an input voltage up to 45 V. The minimum required input
voltage is

requires a minimum input voltage of 4.4 V.
The TLE 4266-2 can supply up to 150 mA. However for protection reasons at high input
voltage above 25 V, the maximum output current is reduced (SOA protection).

TLE 4266-2 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 measuring circuit shown in
capacitor of 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 4266-2 includes the Inhibit function. For a voltage above 3.5 V at the INH pin
the regulator is switched on.
