It has significantly lower quiescent current than previously was available from traditional PNP regulators and allows for a shutdown current (SOIC-8 and TO-263) 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 BYPASS pin (SOIC-8 and TO-263), 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 in adjustable output and fixed-output versions of 1.8 V, 2.5 V, 3 V, 3.3 V, and 5 V. Offered in surface-mount packages of SOT-223, SOIC, and TO-263, the TL5209 is characterized for operation over the virtual junction temperature ranges of –40 °C to 125°C.
