If you need to maintain a steady voltage on your circuit, then this LDO LDS3985M33R linear regulator from STMicroelectronics is perfect for you! Its typical dropout voltage at current is 0.0004@1mA|0.06@150mA|0.15@300mA V. It has an overall accuracy of ±2 %. This voltage regulation device"s single output can produce a current up to 0.55(Typ) A. By only needing an input voltage of 2.5 V with a maximum of 6 V, this is the best way 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. Users like the load regulation of 0.004%/mA. This product will be shipped in tape and reel packaging to allow for quick mounting and safe delivery. Its polarity is positive. The maximum dropout voltage is 0.002@1mA|0.1@150mA|0.25@300mA V. This voltage regulation device has an operating temperature range of -40 °C to 125 °C.
