2 / 20 page TC1014/TC1015/TC1185 DS21335B-page 2 © 2002 Microchip Technology Inc. General Description The TC1014/TC1015/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 50 µA at full load (20 to 60 times lower than in bipolar regulators). The devices’ key features include ultra low noise oper- ation (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 0.5 µA (max) and VOUT falls to zero when the shutdown input is low. The devices incorporate both over-temperature and over-current protection. The TC1014/TC1015/TC1185 are stable with an output capacitor of only 1 µF and have a maximum output current of 50mA, 100mA and 150mA, respectively. For higher output current regulators, please see the TC1107/TC1108/TC1173 (IOUT = 300mA) data sheets.
