Internal and external references
It is possible to set two internal references, 0.6V and 1.2V, or provide an external reference
from 0V to 2.5V. The maximum value of the external reference depends on the V
CC
: with V
CC
=
4V the clamp operates at about 2V (typ.), while with V
CC
greater than 5V the maximum external
reference is 2.5V (typ).

Providing an external reference from 0V to 450mV the output voltage will be regulated but
some restrictions must be considered:
The minimum OVP threshold is set at 300mV.
The under-voltage-protection doesn’t work.
The PGOOD signal remains low.
●

●
To set the resistor divider it must be considered that a 100K pull-down resistor is integrated into
the device (see
Figure 6.
). Finally it must be taken into account that the voltage at the EAREF
pin is captured by the device at the start-up when Vcc is about 4V.
