... ERROR are disabled when the shutdown input is low. The devices incorporate both over-temperature and over-current protection. The TC1054, TC1055 and TC1186 are stable with an output capacitor of only 1µF and have a maximum output current of 50mA, 100mA and 150mA, respectively. For higher output current regulators, please see the TC1173 (I = 300mA) data sheet ...
