Keep the energy stable for every system by using this LDO LD2981ABU33TR linear regulator by STMicroelectronics. Its typical dropout voltage at current is 0.001@0A|0.007@1mA|0.07@25mA|0.18@100mA V. It has an overall accuracy of ±0.75 %. This voltage regulation device's single output can produce a current up to 0.1 A. This will operate at a minimum voltage of 2.5 V and a maximum voltage of 16 V, making it easy to control the power in your circuit. With a fixed output that has a voltage of 3.3 V, this is power management at its best. To produce a constant current at your output, supply your circuit with a line regulation of 0.014%/V. This product will be shipped in tape and reel packaging so that components can be mounted effectively. This voltage regulation device has an operating temperature range of -40 °C to 125 °C. Its polarity is positive. The maximum dropout voltage is 0.003@0A|0.01@1mA|0.1@25mA|0.25@100mA V.
