  The LM39300, LM39301 and LM39302 are 3.0A low-dropout linear voltage regulators that provide a low voltage, high-current output with a minimum of external components. The LM39300/1 offers extremely low dropout (typically 400mV at 3.0A) and low ground current (typically 36mA at 3.0A).
The LM39300/1/2 is ideal for PC add-in cards that need to convert from standard 5V or 3.3V down to new, lower core voltages. A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the LM39300/1/2 to pro-vide 2.5V from a supply as low as 3V.
The LM39300/1/2 also has fast transient response for heavy switching applications.The device requires only 47F of output capacitance to maintain stability and achieve fast transient responseThe LM39300/1 is fully protected with over current limiting,thermal shutdown, reversed-battery protection, reversed-leakage protection, and reversed-lead insertion. The LM39301 offers a TTL-logic compatible enable pin and an error flag that indicates under voltage and over current conditions. Offered in fixed voltages, the LM39300/1/2 comesin the TO-220 and TO-263 packages and is an ideal upgrade to older, NPN-based linear voltage regulators.
