General Description
The TS2940 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 low drop output voltage (Typ. 60mV at light load and 600mV at
800mA). This includes a tight initial tolerance of 2%, extremely good line regulation of 0.05% typ., and very low output
temperature coefficient.
