NOTES:
1. Internal short circuit protection circuitry has been built into the EL2257. See the Applications section.
2. If the disable feature is not desired, tie the ENABLE pins to the V pin, or apply a logic high level to the ENABLE pins.
S
3. The maximum output voltage that can be clamped is limited to the maximum positive output Voltage, or V . Applying a voltage higher than V
OP

inactivates the clamp. If the clamp feature is not desired, either tie the CLAMP pin to the V pin, or simply let the CLAMP pin float.
S
4. The clamp accuracy is affected by V and R . See the Typical Curves Section and the Clamp Accuracy vs V and R curve.
