Notes:
1. The maximum output current is limited only by the external components used and their thermal limitations. For loads greater
than 12.5A, adequate thermal management is required to achieve optimal performance and reliability.
2. Setpoint Accuracy includes Output Ripple/Noise.
3. Cumulative Accuracy is determined by Setpoint Accuracy, Line and Load Regulation, Output Ripple/Noise, Transient
Performance and Temperature Drift.
4. See Typical Operating Characteristics.

Notes:
1. 0 = processor pin connected to VSS. 1 = Open.
2. Setpoint Accuracy includes Output Ripple/Noise.
3. Cumulative Accuracy includes Setpoint Accuracy, Line & Load Regulation, Transient Effects and Temperature Drift.
