Description

The UCC381-3/-5/-ADJ family of positive linear series pass regulators is tailored for low drop out applications where low quiescent power is impor- tant. Fabricated with a BiCMOS technology ideally suited for low input to output differential applications, the UCC381 will pass 1A while requiring only 0.5V of input voltage headroom. Dropout voltage decreases linearly with output current, so that dropout at 200mA is less than 100mV. Quies- cent current is always less than 650µA. To prevent reverse current conduc- tion, on-chip circuitry limits the minimum forward voltage to typically 50mV. Once the forward voltage limit is reached, the input-output differential volt- age is maintained as the input voltage drops until undervoltage lockout dis- ables the regulator.

Features

  This is the inverting input of the transmit gain setting op- erational amplifier. Gain setting resistors are usually con- nected from this pin to TG and from this pin to the analog signal source. The common mode range of the TI+ and TIC pins is from 1.2 V to VDD C 1.2 V. This is an FET gate input.   The TIC pin also serves as one of the transmit input multi- plexer pins when the TI+ pin is connected to VSS. When TI+ is connected to VDD, this pin is ignored. See the pin descrip- tions for the TI+ and the TG pins for more information.
