Introduction

AI Translation

The LD39020 high accuracy voltage regulator provides 200 mA of maximum current from an input voltage ranging from 1.5 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 softstart 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.
