The LD39020ADTPU21R is a linear voltage regulator IC from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 2.1 V with a maximum output current of 200 mA. It operates with an input voltage range of 1.5 V to 5.5 V and features an ultra-low dropout voltage of 200 mV at 200 mA load. The device has a very low quiescent current of 20 ¬µA at no load and can drop to 0.03 ¬µA in shutdown mode, making it suitable for battery-powered applications. This regulator offers an output voltage tolerance of ¬±0.5% and is stabilized with a ceramic capacitor, compatible with a capacitance of 0.47 ¬µF. It includes features such as logic-controlled electronic shutdown, internal soft-start, and optional output voltage discharge. The LD39020ADTPU21R is available in compact DFN4 1x1 and SOT23-5L packages, and it operates within a temperature range of -40 ¬8C to 125 ¬8C. It is suitable for applications in mobile phones, tablets, digital cameras, and other portable devices.
