The TC1265 is a fixed output, high accuracy (typically ±0.5%) CMOS low dropout regulator. Designed specifically for battery-operated systems, the TC1265’s CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 80 µA at full load (20 to 60 times lower than in bipolar regulators!). TC1265 key features include ultra low noise, very low dropout voltage (typically 450 mV at full load), and fast response to step changes in load. The TC1265 incorporates both over-temperature and over-current protection. The TC1265 is stable with an output capacitor of only 1µF and has a maximum output current of 800 mA. It is available in 8-Pin SOIC, 5-Pin TO-220, and 5-Pin DDPAK packages.
