The LD56100 high accuracy voltage regulator provides 1 A of current from an input voltage ranging from 1.8 V to 5.5 V, with a typical dropout voltage of 120 mV. It is available in DFN8 (1.2 x 1.6 mm) package, allowing the maximum space saving. The device is stabilized with a ceramic capacitor on the output. The ultra-low drop voltage, low quiescent current and fast transient response, together with the internal soft-start circuit, make the LD56100 suitable for low power battery-operated applications. An enable logic control function puts the LD56100 in shutdown mode allowing a total current consumption lower than 0.1 μA. Short-circuit protection with current limit foldback and thermal protection are also included.
