1 / 7 page TS39301/2/3/4 1-7 2005/12 rev. A TS39301/2/3/4 3A Ultra Low Dropout Positive Voltage Regulator Low Dropout Voltage 0.4V (typ.) Output Current 3A Low Quiescent Current General Description The TS39301/2/3/4 are 3A ultra low dropout linear voltage regulators that provide low voltage, high current output with a minimum of external components. The TS39301/2/3/4 offers extremely low dropout (typically 400mV at 3A) and low quiescent current (typically 36mA at 3A). The TS39301/2/3/4 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 TS39301/2/3/4 to provide 2.5V from a supply as low as 3V, and 1.8V from a supply as low as 2.5V. The TS39301/2/3/4 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 TS39301/2/3/4, the enable pin may be tied to input voltage if it is not required for enable control. This series are offered in 5-pin TO-220, TO-263 package. Features Dropout voltage typically 0.4V @Io=3A Output current up to 3A Low ground current Current limiting and Thermal shutdown Extremely fast transient response Reversed leakage protection Reverse battery protection TTL/CMOS compatible enable pin Error flag output (TS39301 only) Adjustable version (TS39302 only) Output voltage sense (TS39303 / 4 only) Ordering Information Note: Where xx denotes voltage option, available are 50 = 5.0V 33 = 3.3V 25 = 2.5V 18 = 1.8V Part No. Operating Temp.
