Device Overview

Summary

The TC2014, TC2015, and TC2185 are high accuracy (typically ±0.4%) CMOS upgrades for older (bipolar) low dropout regulators such as the LP2980. Total supply current is typically 55µA (20 to 60 times lower than in bipolar regulators). The devices’ key features include ultra low noise operation (plus bypass reference), very low dropout voltage - typically 45mV (TC2014); 90mV (TC2015); and 140mV (TC2185) at full load - and fast response to step changes in load. Supply current is reduced to 0.5µA (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 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.
