Package
The TL5209 device is 500-mA low-dropout (LDO) regulator that is well suited for portable applications. It has a lower quiescent current than most traditional PNP regulators and allows for a shutdown current of 0.05 μA (typical). The TL5209 also has very good dropout voltage characteristics, requiring a maximum dropout of 10 mV 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.
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.
