TS2937 500mA Ultra Low Dropout Fixed Positive Voltage Regulator TO-263 Low Dropout Voltage 0.6V max. Pin assignment: 1. Input 2. Ground 3. Output General Description The TS2937 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 very low ground current (100uA Typ.) and very low drop output voltage (Typ. 60mV at light load and 600mV at 500mA). This includes a tight initial tolerance of 1% typ., extremely good line regulation of 0.05% typ., and very low output temperature coefficient. This series is offered in 3-pin TO-263, TO-220, TO-252 & SOT-223 package. Features Dropout voltage typically 0.6V @Io=500mA Output current up to 500mA Output voltage trimmed before assembly -18V Reverse peak voltage +30V Input over voltage protection +60V Transient peak voltage Internal current limit Thermal shutdown protection Block Diagram Ordering Information Part No. TS2937CZxx TS2937CMxx TS2937CPxx -20 ~ +85 C o Operation Temp.
