TC1017-3.3VCTTR

The 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 reduction versus the popular SOT-23 package and is offered in two pinouts to make board layout easier. Developed specifically for battery-powered systems, the TC1017’s CMOS construction consumes only 53 μA typical supply current over the entire 150 mA operating load range. This can be as much as 60 times less than the quiescent operating current consumed by bipolar LDOs. The TC1017 is designed to be stable, over the entire input voltage and output current range, with low-value (1 μF) ceramic or tantalum capacitors. This helps to reduce board space and save cost. Additional integrated features, such as shutdown, overcurrent and overtemperature protection, further reduce the board space and cost of the entire voltage-regulating application. Key performance parameters for the TC1017 include low dropout voltage (285 mV typical at 150 mA output current), low supply current while shutdown (0.05 μA typical) and fast stable response to sudden input voltage and load changes.
