SEMIRS3221-3.0YF5 is a SOT-23-5 Linear Voltage Regulator (LDO) with an output voltage of 3.0V, manufactured by RUNIC SEMI. It is an upgraded version of the RS3221-3.0YF4. The device offers low dropout voltage, wide operating temperature range, low quiescent current, and high PSRR. The device provides voltage regulation and over current protection with thermal shutdown. It is RoHS compliant, meeting environmental regulations. An ultra-small SOT-23-5 package enables high density applications. The device offers superior transient characteristics and is ideal for low voltage and low power applications such as cell phones, PDAs, digital cameras, and personal digital assistants. It is suitable for battery-powered applications, and also for circuit designs that require minimum energy consumption.
