General Description
The TS39300 series are 3A ultra low dropout linear voltage regulators that provide low voltage, high current output
with a minimum of external components. The TS39300 offers extremely low dropout (typically 400mV at 3A) and low
ground current (typically 36mA at 3A).
The TS39300 is ideal for PC add-in cards that need to convert from standard 3.3V to 2.5V or 2.5V to 1.8V. A
guaranteed maximum dropout voltage of 500mV over all operating conditions allows the TS39300 to provide 2.5V
from a supply as low as 3V, and 1.8V from a supply as low as 2.5V. The TS39300 also has fast transient response for
heavy switching applications. The device requires only 47uF of output capacitor to maintain stability and achieve fast
transient response.
