General Description
The TC2117 is a fixed, high accuracy (typically ±0.5%) CMOS low dropout regulator. Designed specifically for battery operated systems, the TC2117’s CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 80 A at full load (20 to 60 times lower than in bipolar regulators). TC2117 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 TC2117 incorporates both overtemperature and overcurrent protection. The TC2117 is stable with an output capacitor of only 1F and has a maximum output current of 800 mA. This device is available in 3-Pin SOT-223, and 3-Pin DDPAK packages.
