The LM39500 offers extremely low dropout (typically
400mV at 5A) and low ground current (typically 70mA
* X.X = Fixed Vout = 1.5V, 1.8V, 2.5V, 3.3V, 5.0V
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 allows the LM39500/1/2 to
provide LM39500/1/2 to 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 response.
The 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.
