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

OUT) where FLG becomes active (low) when CTL is low. OUT is pulled high by a 100k external

resistor to V

IN.
