TS2937 Taiwan Semiconductor 500mA Ultra Low Dropout Voltage Regulator DESCRIPTION FEATURES TS2937 of fixed-voltage monolithic micro-power voltage This device excellent choice of use in battery-power ● ● ● Dropout voltage typically 0.6V @ Io=500mA Output voltage trimmed before assembly -18V Reverse peak voltage application. current ● +30V Input over voltage protection increases on slightly at dropout, which prolongs battery ● ● ● +60V Transient peak voltage Internal current limit Thermal shutdown protection regulators is designed for a wide range of applications. Furthermore, the quiescent life. This series of fixed-voltage regulators features very low ground current (200uA Typ.) and very low drop output voltage (Typ. 60mV at light load and 600mV at 500mA). This includes a tight initial tolerance of 2%, APPLICATION extremely good line regulation of 0.05% typ., and very ● Post Regulator for SMPS low output temperature coefficient. ● Industrial Instrumentation TO-220 2 TO-263 (D PAK) TO-252 (DPAK) SOT-223 Pin Definition: 1.
