LD39020 Quiescent Current Linear Regulators

STMicroelectronics LD39020 Very Low Quiescent Current Linear Regulators are a high accuracy voltage regulator that provides 200mA of maximum current from an input voltage ranging from 1.5V to 5.5V, with a typical dropout voltage of 200mV. These devices are stabilized with a ceramic capacitor on the output. The ultra low drop voltage, low quiescent current and low noise features, together with the internal soft-start circuit, make the LD39020 suitable for low power battery-operated applications.
