TS2940

TS2940 1A Ultra Low Dropout Fixed Positive Voltage Regulator TO-263 Low Dropout Voltage 0.6V (typ.) Pin assignment: 1. Input 2. Ground 3. Output General Description The TS2940 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 1A). 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.
