Package Type 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 con- struction eliminates wasted ground current, signifi- cantly extending battery life. Total supply current is typically 80 µA at full load (20 to 60 times lower than in bipolar regulators). TC2117 key features include ultra low noise, very low dropout voltage (typically 450mV at full load), and fast response to step changes in load. The TC2117 incor- porates both over-temperature and over-current pro- tection. The TC2117 is stable with an output capacitor of only 1 µF and has a maximum output current of 800mA. This device is available in 3-Pin SOT-223, and 3-Pin DDPAK packages.
