DESCRIPTION

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).

* X.X = Fixed Vout = 1.5V, 1.8V, 2.5V, 3.3V, 5.0V

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.
