3. Protection
VREG pin ground-short operation
Note) The characteristics listed below are reference values derived from the design of the IC and are not guaranteed.
(3.3 V line)
VREG pin is an output pin of LDO used in internal circuits. The operation of each function stops just after VREG pin
is shorted to GND. Since each function is not latched unlike the case of [3.Protection : Protection sequence], it
recovers by the release of ground-short.
The operation is as follows.
