Stable voltages are always needed for sensitive systems implement this LDO LP2989AIM-2.5/NOPB linear regulator from Texas Instruments. Its typical dropout voltage at current is 0.001@0.1mA|0.15@200mA|0.31@500mA V. It has an overall accuracy of ±0.75 %. This voltage regulation device"s single output can produce a current up to 0.5 A. This will operate at a minimum voltage of 2.1 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 2.5 V, this is power management at its best. Maintain a constant voltage level with a load regulation of 0.4%(Typ) and line regulation of 0.014%/V. In order to ensure parts aren"t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. Its polarity is positive. This voltage regulation device has an operating temperature range of -40 °C to 125 °C. The maximum dropout voltage is 0.003@0.1mA|0.2@200mA|0.425@500mA V.
