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:
