TS2937CP-3.3 Taiwan Semiconductor

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