Inhibit General Description The TS2938 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.), very low drop output voltage (Typ. 60mV at light load and 600mV at 500mA) and output inhibit control. This includes a tight initial tolerance of 2%, extremely good line regulation of 0.05% typ., and very low output temperature coefficient.
