1. Internal short circuit protection circuitry has been built into the EL2257C/EL2357C. See the Applications section.
2. If the disable feature is not desired, tie the ENABLE pins to the VS pin, or apply a logic high level to the ENABLE pins.
3. The maximum output voltage that can be clamped is limited to the maximum positive output Voltage, or VOP. Applying a Voltage higher than VOP
inactivates the clamp. If the clamp feature is not desired, either tie the CLAMP pin to the VS pin, or simply let the CLAMP pin float.
4. The clamp accuracy is affected by VIN and RL. See the Typical Curves Section and the Clamp Accuracy vs. VIN and RL curve.
