This LDO LD3985M122R linear regulator developed by STMicroelectronics keeps the power stable! It has an overall accuracy of ±4 %. Its typical dropout voltage at current is 0.0004@1mA|0.02@50mA|0.045@100mA|0.06@150mA V. This voltage regulation device's single output can produce a current up to 0.55(Typ) A. It only needs a voltage of at least 2.5 V while not exceeding 6 V to effectively power your circuit. With a fixed output that has a voltage of 1.22 V, this is power management at its best. Operate at a constant current by utilizing the load regulation of 0.008%/mA and line regulation of 0.1%/V. Tape and reel packaging will encase the product during shipment, ensuring safe delivery and enabling quick mounting of components. The maximum dropout voltage is 0.002@1mA|0.035@50mA|0.07@100mA|0.1@150mA V. Its polarity is positive. This voltage regulation device has an operating temperature range of -40 °C to 125 °C.
