超低ドロップ・アウト（ULDO）レギュレータ  

ST offers a wide range of low and medium power LDO regulators featuring ultra-low dropout and fast transient response characteristics. The ultra-low dropout series of LDOs simplifies the design of high-efficiency, cost-effective linear power management (from 50 mA to 3 A of continuous load current), ideal for DSPs, MCUs and FPGAs.
