CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

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
S
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 V
OP
. 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
S
pin, or simply let the CLAMP pin float.
4. The clamp accuracy is affected by V
IN
and R
L
. See the Typical Curves Section and the Clamp Accuracy vs V
IN
and R
L
curve.
