General Description
TS39300/1/2/3 are 3A ultra low dropout linear voltage regulators that provide low voltage, high current output with a
minimum of external components. The TS3930x series offers extremely low dropout (typically 400mV at 3A) and low
quiescent current (typically 36mA at 3A).
TS39300/1/2/3 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 TS39300/1/2/3 to provide
2.5V from a supply as low as 3V, and 1.8V from a supply as low as 2.5V. The TS39300/1/2/3 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.
On the TS39300/1/2/3, the enable pin may be tied to input voltage if it is not required for enable control.
