Description

The TC1108 is a fixed output, high accuracy (typically ±0.5%) CMOS low dropout regulator. Total supply current is typically 50 A at full load (20 to 60 times lower than in bipolar regulators). TC1108 key features include ultra low noise, very low dropout voltage (typically 240 mV at full load) and fast response to step changes in load. The TC1108 incorporates both over-temperature and over-current protection. The TC1108 is stable with an output capacitor of only 1F and has a maximum output current of 300 mA. It is available in a SOT-223 package.
