The TC1014/TC1015/TC1185 are high accuracy(typically ±0.5%) CMOS upgrades for older (bipolar)Low Dropout Regulators (LDOs) such as the LP2980.Designed specifically for battery-operated systems, thedevices’ CMOS construction eliminates wasted groundcurrent, significantly extending battery life. Total supplycurrent is typically 50 μA at full load (20 to 60 timeslower than in bipolar regulators).The devices’ key features include ultra low-noiseoperation (plus optional Bypass input), fast response tostep changes in load, and very low dropout voltage,typically 85 mV (TC1014), 180 mV (TC1015), and270 mV (TC1185) at full-load. Supply current isreduced to 0.5 μA (max) and VOUT falls to zero whenthe shutdown input is low. The devices incorporate bothovertemperature and overcurrent protection.The TC1014/TC1015/TC1185 are stable with an outputcapacitor of only 1 μF and have a maximum outputcurrent of 50 mA, 100 mA and 150 mA, respectively.For higher output current regulators, please see theTC1107 (DS21356), TC1108 (DS21357), TC1173(DS21362) (IOUT = 300 mA) data sheets.
