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.
