... OUT 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 1µF and have a maximum output current of 50mA, 100mA and 150mA, respectively. For higher output current regulators, please see the TC1107/TC1108/TC1173 (I = 300mA) data sheets ...

... The regulator enters shutdown when a logic low is applied to this input. During shutdown, output voltage falls to zero, ERROR is open circuited and supply current is reduced to 0.5µA (max). 4 Bypass Reference bypass input.

... DETAILED DESCRIPTION The TC1014/TC1015/TC1185 are precision fixed output voltage regulators. (If an adjustable version is desired, please see the TC1070/TC1071/TC1187 data sheet.) Unlike bipolar regulators, the TC1014/TC1015/ TC1185 supply current does not increase with load current. In addition, V remains stable and within OUT regulation over the entire 0mA to I ...
