TC1186

The TC1054, TC1055, and TC1186 are high accuracy (typically ±0.5%) CMOS upgrades for older (bipolar) low dropout regulators. Designed specifically for battery-operated systems, the devices’ CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 50µA at full load (20 to 60 times lower than in bipolar regulators!). The devices’ key features include ultra low noise operation, very low dropout voltage — typically 85mV (TC1054); 180mV (TC1055); and 270mV (TC1186) at full load — and fast response to step changes in load. An error output (ERROR) is asserted when the devices are out-of-regulation (due to a low input voltage or excessive output current). ERROR can be used as a low battery warning or as a processor RESET signal (with the addition of an external RC network). Supply current is reduced to 0.5µA (max) and both VOUT and ERROR are disabled when the shut-down input is low. The devices incorporate both over-temperature and over-current protection. The TC1054, TC1055, and TC1186 are stable with an output capacitor of only 1µF and have a maximum output current of 50mA, 100mA, and 150mA, respectively. For higher output current regulators, please see the TC1173 (IOUT = 300mA) data sheet.
