  TC1014/1015/1185 Data Sheet

The TC1014, TC1015, and TC1185 are high accuracy (typically ±0.5%) CMOS upgrades for older (bipolar) low dropout regulators such as the LP2980. 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!). Key features for the devices include ultra low-noise operation (plus optional Bypass input), fast response to step changes in load, and very low dropout voltage, typically 85mV (TC1014), 180mV (TC1015), and 270mV (TC1185) at full load. Supply current is reduced to 0.5µA (max) and VOUT falls to zero when the shutdown input is low. The devices also incorporate both over-temperature and over-current protection. The TC1014, TC1015, and TC1185 are stable with an output capacitor of only 1µF and have a maximum output current of 50mA, 100mA, and 150mA, respectively. For higher output versions, see the TC1107, TC1108, and TC1173 (IOUT = 300 mA) data sheets.
