1A Adjustable/Fixed Low Dropout Linear Regulator

Note 1: Typical Values represent the most likely parametric norm.

Note 2: All limits are guaranteed by testing or statistical analysis.

Note 3: Load and line regulation are measured at constant junction room temperature.

Note 4: The minimum output current required to maintain regulation.
