DESCRIPTION/ORDERING INFORMATION
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 (SOIC-8 and TO-263) of only 0.05
μ
A (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.

Packages: SOT-223, SOIC-8, and TO-263
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.
