The TL5209 is an efficient PNP low-dropout (LDO) regulator that is well suited for portable applications. It has significantly lower quiescent current than previously was available from traditional PNP regulators and allows for a shutdown current of only 0.05 µA (typical). The TL5209 also has very good dropout voltage characteristics, requiring a maximum dropout of 60 mV at light loads and 500 mV at full load. In addition, the LDO also has 1% output voltage accuracy and extremely tight line and load regulation that is hard to match by its CMOS counterparts.

For noise-sensitive applications, the TL5209 allows for low-noise capability via 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.

The TL5209 is available with adjustable output. Offered in an SOIC-8 surface-mount package, the TL5209 is characterized for operation over the virtual junction temperature ranges of -40°C to 125°C.
