TS2937 500mA Ultra Low Dropout Voltage Regulator TO-220 TO-263 2 (D PAK) TO-252 (DPAK) SOT-223 Pin Definition: 1. Input 2. Ground 3. Output General Description TS2937 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 (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%, extremely good line regulation of 0.05% typ., and very low output temperature coefficient.
