General Description

The TC1017 is a high-accuracy (typically ±0.5%) CMOS upgrade for bipolar low dropout regulators. It is offered in a SC-70 or SOT-23 package. The SC-70 package represents a 50% reduced footprint versus the popular SOT-23 package.

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.
