Note 1: Common-mode performance tends to follow the typical value. Minimum value limits reflect performance

only near the supply rails.

2: Continuous short circuit may exceed absolute maximum TJ under some conditions.

3: Shorting OUT to V+ when V+ > 12V may damage the device.

4: RL connected to 5.0V. Sourcing: 5V ≤ VOUT ≤ 12V. Sinking: 2.5V ≤ VOUT ≤ 5V.
