Standard Application Circuit
+Vin
R-78HBxx-0.5
+Vout
Add a blocking diode to
Vout if current can flow
backwards into the out-
put, as this can damage
the converter.
-Vin
-Vout
The converter has a built in soft start circuit. Rapidly changing the input voltage
from Vin(min) Vin(max) can bypass this circuit and damage the converter.
