LD2985 SERIES
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 160µA. R1 and R2
resistors are implanted type; typical values are, respectively, 42.6 KΩ and 51.150 KΩ.
