Description

TC1264 is a fixed output, high accuracy (typically ±0.5%) CMOS low dropout regulator. Designed specifically for battery-operated systems, the TC1264's CMOS construction eliminates wasted ground current, significantly extending battery life. Supply current is typically 80 A at full load (20 to 60 times lower than in bipolar regulators!). TC1264 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 TC1264 incorporates both over-temperature and over-current protection. The TC1264 is stable with an output capacitor of only 1F and has a maximum output current of 800 mA. It is available in 3-Pin SOT-223, 3-Pin TO-220 and 3-Pin DDPAK packages.
