Reverse current

The power transistor used in the LD2985 has not an inherent diode connected between the

regulator input and output. If the output is forced above the input, no current will flow from

the output to the input across the series pass transistor. When a VREV voltage is applied on

the output, the reverse current measured flows to the GND across the two feedback

resistors. This current typical value is 160 µA. R1 and R2 resistors are implanted type;

typical values are, respectively, 42.6 k

Ω and 51.150 kΩ.
