The LN2220PAR with SOT-23-6L DC-DC Converter ROHS from NATIONAL LINEAR is a low voltage regulator designed for use in low voltage circuits. Its low cost and small size make it ideal for use in a wide variety of applications. It can be used to regulate both input and output voltage levels of the device, as it features up to a 90% efficiency rating. It also features undervoltage, max input voltage, and overvoltage protection, as well as an internally trimmed output voltage. Its RoHS compliant manufacturing process also helps ensure that its operation is reliable and safer for the environment than other converter designs.
