NOTES:

1. CLAMP pin and ENABLE pin specifications apply only to the EL2157.

2. Internal short circuit protection circuitry has been built into the EL2150/EL2157. See the Applications section.

3. If the disable feature is not desired, tie the ENABLE pin to the VS pin, or apply a logic high level to the ENABLE pin.

4. 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.
