General Note: Devices are ESD protected, however, handling precautions recommended.
General Note: All limits guaranteed by testing or statistical analysis.
Note 1: MIC2505-1 and -2 versions have no open load detect feature.
Note 2: Open-load threshold is the output voltage (V
) where FLG becomes active (low) when CTL is low. OUT is pulled high by a 100k external

resistor to V
