This LDO LD39050PU33R linear regulator from STMicroelectronics gives you control over the voltage levels of your circuit. It has an overall accuracy of ±2 %. Its typical dropout voltage at current is 0.2@500mA V. This voltage regulation device"s single output can produce a current up to 0.5 A. Using the part will provide the power your application needs by requiring a voltage only of 1.5 V and not exceeding a voltage of 5.5 V. With a fixed output that has a voltage of 3.3 V, this is power management at its best. Maintain a constant voltage level with a load regulation of 0.002%/mA(Typ) and line regulation of 0.01%/V(Typ). This product will be shipped in tape and reel packaging so that components can be mounted effectively. The maximum dropout voltage is 0.4@500mA V. This voltage regulation device has a minimum operating temperature of -40 °C and a maximum of 125 °C. Its polarity is positive.
