The TS4274 series of fixed-voltage monolithic micro-power voltage regulators is designed for a wide r ange of applications . This device excellent choice of use in battery-power application. Further more, the quiescent current increases on slightly at dropout, which prolongs battery life. This series of fixed-voltage regulators features very low ground current (200uA Typ.) and very low drop output voltage (600mV at 400mA). This includes a tight initial toleranc e of 2% typ., and very low output temperature coefficient.
