Reverse current
The power transistor used in the LD2980 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
the output, the reverse current measured, according to the test circuit in
the GND across the two feedback resistors. This current typical value is 160 µA. R
resistors are implanted type; typical values are, respectively, 42.6 kΩ and 51.150 kΩ.
