GENERAL DESCRIPTION
The TC1108 is a fixed output, high accuracy (typically
±0.5%) CMOS low dropout regulator. Total supply current is
typically 50µA at full load (20 to 60 times lower than in bipolar
regulators!).
TC1108 key features include ultra low noise, very low
dropout voltage (typically 240mV 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 1µF and
has a maximum output current of 300mA. It is available in a
SOT-223 package.
