DESCRIPTION
The LM39500, LM39501 and LM39502 is a 5A
low-dropout linear voltage regulator that provides
a low-voltage, high-current output with a
minimum of external components. Utilizing Super
* X.X = Fixed Vout = 1.5V, 1.8V, 2.5V, 3.3V, 5.0V
beta PNP pass element, The LM39500 offers
extremely low dropout (typically 400mV at 5A)
and low ground current (typically 70mA at 5A).
The LM39500/1/2 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 LM39500/1/2 to provide 2.5V from a supply as low as 3V. The LM39500 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 LM39500/1/2 is fully protected with overcurrent
limiting,thermal shutdown, reversed-battery and reversed-lead in-sertion protection. The LM39501 offers a
TTL-logic-compat-ible enable pin and an error flag that indicates undervoltage and overcurrent
conditions. The LM39500/1/2 comes in the TO-220 and TO-263 packages and is an ideal upgrade to
older,NPN-based linear voltage regulators.
The LM39502 is adjustable version.
