Features
TC2014/2015/2185
General Description
The TC2014, TC2015 and TC2185 are high-accuracy (typically ±0.4%) CMOS upgrades for bipolar low dropout regulators, such as the LP2980. Total supply current is typically 55 A; 20 to 60 times lower than in bipolar regulators. The key features of the device include low noise operation (plus bypass reference), low dropout voltage – typically 45 mV for the TC2014, 90 mV for the TC2015, and 140 mV for the TC2185, at full load – and fast response to step changes in load. Supply current is reduced to 0.5 A (max) and VOUT falls to zero when the shutdown input is low. The devices also incorporate over-current protection. The TC2014, TC2015 and TC2185 are stable with an output capacitor of 1 F and have a maximum output current of 50 mA, 100 mA and 150 mA, respectively. For higher output versions, see the TC1107 (DS21356), TC1108 (DS21357) and TC1173 (DS21362) (IOUT = 300 mA) datasheets.
