The MIC5156/5157/5158 Super LDO Regulator Controllers provide a single-chip solution for high-current, low-dropout linear voltage regulation. Utilizing an external N-channel power MOSFET, these controllers achieve a low dropout voltage and high output current capabilities. The MIC5157 and MIC5158 incorporate an internal charge pump tripler for gate drive voltage, simplifying the design and reducing external component count. Applications include ultralow dropout voltage regulation, constant high-current sources, and low-noise SMPS post regulators.
