General Description
The TS4274 series of fixed-voltage monolithic micro-power voltage regulators is designed for a wide range of
applications. This device excellent choice of use in battery-power application. Furthermore, 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 tolerance of 2% typ., and very low output temperature coefficient.
