This LDO LD39100PUR linear regulator developed by STMicroelectronics keeps the power stable! Its typical dropout voltage at current is 0.2@1A V. This voltage regulation device"s single output can produce a current up to 1 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 an adjustable output that has a voltage of 0.8(Min) 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). Tape and reel packaging will encase this product during shipment, in order to ensure safe delivery and enable quick mounting of components. The maximum dropout voltage is 0.4@1A V. This voltage regulation device has a minimum operating temperature of -40 °C and a maximum of 125 °C. Its polarity is positive.
