... MOSFET is fully enhanced, an additional higher supply voltage is required to produce the necessary gate-to-source enhancement. This higher gate drive voltage is provided by an external gate drive supply (MIC5156 internal charge pump (MIC5157 and MIC5158). Gate Drive Supply Voltage (MIC5156 only) The gate drive supply voltage must not be more than 14V ...

... Standard N-channel enhancement-mode MOSFETs are ac- ceptable for most Super LDO regulator applications. Logic-level N-channel enhancement-mode MOSFETs may be necessary if the external gate drive voltage is too low (MIC5156), or the input voltage is too low, to provide adequate charge pump voltage (MIC5157/8) to enhance a standard MOSFET. Circuit Layout For the best voltage regulation, place the source, ground, and error amplifi ...

... Some linear regulators specify a minimum required output filter capacitance because the capacitor determines the dominant pole of the system, and thereby stabilizes the system. This is not the situation for the MIC5156/7/8; its dominant pole is determined within its error amplifier ...

... The Super LDO regulator can pro- vide a significant reduction in peak-to-peak ripple voltage. High-Current Switch Application All versions of the MIC5156/7/8 may be used for current-lim- ited, high-current, high-side switching with or without voltage regulation. See figure (4a). Simply leave the “S” terminal open ...
