产品概述
描述
The LD39020 high accuracy voltage regulator provides 200 mA of maximum current from an input voltage ranging from 1.5 V to 5.5 V, with a typical dropout voltage of 200 mV. It is available in DFN4 1x1 and SOT23-5L packages, 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 low noise features, together with the internal soft-start circuit, make the LD39020 suitable for low power battery-operated applications.
An enable logic control function puts the LD39020 in shutdown mode allowing a total current consumption lower than 0.1 µA. Constant current and thermal protection are provided.
