A low-dropout (LDO) voltage regulator with a high PSRR and low noise is available under the model number TPS76930DBVR (power supply rejection ratio)T. It is a fixed-output regulator that runs at 3.0V and has an output current capacity of up to 100 mA. The device's tiny SOT-23-5 size makes it perfect for applications with limited space.
