(Plastic Package)
Order Code: STV8164
The adjustable value of the third output can be fixed
from 2.5 V to 16 V.
An internal reset circuit generates a reset pulse
when the voltage of Output 1 drops below the
regulated voltage value.
Short-circuit and thermal protections are included in
all versions.
Outputs 2 and 3 can be disabled by a digital input.
