Application notes
LD2985 series

5.6
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 V
REV
voltage is applied on
the output, the reverse current measured flows to the GND across the two feedback
resistors. This current typical value is 160μA. R
1
and R
2
resistors are implanted type; typical
values are, respectively, 42.6 K
and 51.150 K
.
