This LDO LP2989IMX-1.8/NOPB linear regulator from Texas Instruments gives you control over the voltage levels of your circuit. It has an overall accuracy of ±1.25 %. This voltage regulation device"s single output can produce a current up to 0.5 A. With a small input voltage of 2.1 V and a max of 16 V, this will supply sufficient power to your circuit. With a fixed output that has a voltage of 1.8 V, this is power management at its best. At a load regulation of 0.4%V(Typ) and line regulation of 0.014%/V a constant current can be produced at the output of your circuit. This product will be shipped in tape and reel packaging so that components can be mounted effectively. Its polarity is positive. This voltage regulation device has a minimum operating temperature of -40 °C and a maximum of 125 °C.
