LD2982 SERIES
10/13
REVERSE CURRENT
The power transistor used in the LD2982 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
.
