TC1017 pdf datasheet

General DescripTIonThe TC1017 is a high-accuracy (typically ±0.5%)CMOS upgrade for bipolar Low Dropout regulators(LDOs). It is offered in a SC-70 or SOT-23 package.The SC-70 package represents a 50% footprint reducTIonversus the popular SOT-23 package and is offeredin two pinouts to make board layout easier.Developed specifically for battery-powered systems,the TC1017’s CMOS construcTIon consumes only53 μA typical supply current over the enTIre 150 mAoperating load range. This can be as much as 60 timesless than the quiescent operating current consumed bybipolar LDOs.The TC1017 is designed to be stable, over the entireinput voltage and output current range, with low-value(1 μF) ceramic or tantalum capacitors. This helps toreduce board space and save cost. Additional integratedfeatures, such as shutdown, overcurrent andovertemperature protection, further reduce the boardspace and cost of the entire voltage-regulatingapplication.Key performance parameters for the TC1017 includelow dropout voltage (285 mV typical at 150 mA outputcurrent), low supply current while shutdown (0.05 μAtypical) and fast stable response to sudden inputvoltage and load changes.
