TPS3124J18DBVTG4 Datasheet

In general this is not enough current to damage most ICs which the RC4194 might be supplying, but it is a potentially destructive condition. Fortunately, it is easy to protect against. As shown in the typical application circuit in Figure 11, a diode, D, can be connected to the negative output.
