Application ideas
12/17
When an output voltage below the internal reference (1.235 V) is required, the circuit
reported in the figure 18 can been used. In this case the minimum voltage reachable is 0.6 V
and can be easily calculated with the following formula:
V
If the load is not present, a resistor connected between V
to avoid that the voltage across C
The value of this resistor has to be calculated taking into account that the current flowing
through this resistance has to be higher than the current flowing through R
