TC1186-3.3VCT713

The TC1186 is high accuracy (typically ±0.5%) CMOS upgrades for older (bipolar) low dropout regulators. 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 270 mV (TC1186) at full load — and fast response to step changes in load. An error output (ERROR) is asserted when the devices are outof-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 TC1186 is stable with an output capacitor of only 1 µF and have a maximum output current of 150 mA. For higher output current regulators.
