The VRH1802LLX is a low dropout regulator (LDO) LLP-4 RoHS manufactured by AnaSem. It is designed to provide reliable power supply solutions for a wide range of devices, including personal electronics, automotive electronics, and industrial electronics. It is RoHS compliant and is available in TO220-5, SOT89-3, SOT223-4 and SO77-2 package styles. Its features include: low operating current, low noise, high accuracy current and voltage reference, enable and power-on reset output, and thermal shutdown protection. It also has an adjustable output voltage feature ranging from 0.8V to 24V and can operate up to 3A with an SC-80 package. The dropout voltage of the regulator is typically very low, making it an ideal choice to decrease system consuming power.
