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 V
3. The maximum output voltage that can be clamped is limited to the maximum positive output Voltage, or V
4. The clamp accuracy is affected by V
