... I ( max) OUT Where I (max) is the maximum output current and R OUT is the current sense resistor. For example, the MIC5159-1.8BM6 is used with an external MOSFET to form a 5A LDO with an input of 2.5V. Either a 2.5V or 1.8V gate threshold MOSFET can be selected. The minimum R is calculated as: DS(ON) 2.5V 1.8V R 10m ...

... Output Capacitor The MIC5159 requires an output capacitor to maintain stabil- ity and improve transient response. Proper selection is impor- tant to ensure proper operation. The MIC5159 output capaci- tor selection is highly dependent upon the components and the application. With a very high gate charge (gate capaci- tance) MOSFET, the output requires a much larger valued ceramic capacitor for stability ...

... Trace resistance will increase dropout voltage. This is more of a factor at higher output currents. Also, a minimum amount of distance between the gate pin, on the MIC5159, and the P-Channel MOSFET gate is recom- mended. A long trace can create a small parasitic inductor. This, coupled to the gate capacitance of the MOSFET, can create a high frequency tank circuit ...
