Designed specifically for battery-operated systems, the devices’ CMOS construction eliminates wasted ground current, significantly 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 ultra low-noise operation (plus optional Bypass input), fast response to step changes in load, and very low dropout voltage, typically 85 mV (TC1014), 180 mV (TC1015), and 270 mV (TC1185) at full-load. Supply current is reduced to 0.5 µA (max) and VOUT falls to zero when the shutdown input is low. The devices incorporate both overtemperature and overcurrent protection. The TC1014/TC1015/TC1185 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 see the TC1107 (DS21356), TC1108 (DS21357), TC1173 (DS21362) (IOUT = 300 mA) data sheets.
