TS2940 Taiwan Semiconductor 1A Ultra Low Dropout Voltage Regulator GENERAL DESCRIPTION FEATURES The TS2940 series of fixed-voltage monolithic micropower 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. ● Dropout voltage typically 0.6V @ Io=800mA ● Output current up to 1A ● Output voltage trimmed before assembly ● -18V Reverse peak voltage ● +30V Input over voltage protection ● +60V Transient peak voltage ● Internal current limit ● Thermal shutdown protection TO-220 2 TO-263 (D PAK) APPLICATION ● Post Regulator for SMPS ● Industrial Instrumentation TO-252 (DPAK) SOT-223 Pin Definition: 1.

The case thermal reference is defined at the solder mounting surface of the drain pins. RӨJA is guaranteed by design while RӨCA is determined by the user’s board design. RӨJA shown below for single device operation on FR-4 PCB in still air.
