Description

The TC1107 is a fixed output, high accuracy (typically ±0.5%) CMOS upgrade for older (bipolar) low dropout regulators. Total supply current is typically 50µA at full load (20 to 60 times lower than in bipolar regulators). TC1107 key features include ultra low noise operation (plus optional Bypass input); very low dropout voltage (typically 240 mV at full load), and fast response to step changes in load. Supply current is reduced to 0.05 µA (typical) and VOUT falls to zero when the shutdown input is low. The TC1107 incorporates both over-temperature and over-current protection. The TC1107 is stable with an output capacitor of only 1µF and has a maximum output current of 300 mA.
