MICROCHIP TC1016-4.0VLTTR

The TC1016 is a high-accuracy (typically ±0.5%), CMOS upgrade for bipolar low dropout regulators (LDOs). The TC1016 is offered in both the SC-70 and SOT-23 packages. The SC-70 package represents a 50% footprint reduction versus the popular SOT-23 package. Developed specifically for battery-powered systems, the device’s CMOS construction consumes only 53 μA typical supply current over the entire 80 mA operating load range. This can be as much as 60 times less than the quiescent operating current consumed by bipolar LDOs. With small-space requirements and cost in mind, the TC1016 was developed to be stable over the entire input voltage and output current operating range using low value (1 μF ceramic), low Equivalent Series Resistance (ESR) output capacitors. Additional integrated features (such as shutdown, overcurrent and overtemperature protection) further reduce board space and cost of the entire voltage-regulating application. Key performance parameters for the TC1016 are low drop out voltage (150 mv (typ.) at 80 mA output current), low supply current while shutdown (0.05 μA typical) and fast stable response to sudden input voltage and load changes.
