Designed specifically for battery-operated systems, the devices’ CMOS construction minimizes ground current, extending battery life. Total supply current is typically 50 µA at full load (20 to 60 times lower than in bipolar regulators). The devices’ key features include low noise operation, low dropout voltage – typically 85 mV (TC1054), 180 mV (TC1055) and 270 mV (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 0.5 µA (max), with both VOUT and ERROR disabled when the shutdown 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 1 µF and have a maximum output current of 50 mA, 100 mA and 150 mA, respectively. For higher output current regulators, please refer to the TC1173 (IOUT = 300 mA) data sheet (DS21632).
