TL5209DR

The TL5209DR is a 500mA single output adjustable low noise LDO Regulator suitable for portable applications. It has a lower quiescent current than most traditional PNP regulators and allows for a shutdown current of 0.05µA (typical). The TL5209 also has very good dropout voltage characteristics, requiring a maximum dropout of 10mV at light loads and 500mV at full load. In addition, the LDO also has a 1% output voltage accuracy and very tight line and load regulation that is comparable to its CMOS counterparts. For noise-sensitive applications, the TL5209 allows for low-noise capability through an external bypass capacitor connected to the BYP pin, which reduces the output noise of the regulator. Other features include current limiting, thermal shutdown, reverse-battery protection and low temperature coefficient.
