DESCRIPTION
The LD1580 is a very low dropout positive linear
voltage
regulator
particularly
applications requiring output currents up to 7 A.
The LD1580 typical dropout voltage is 400mV at
7A
while
it
lighter loads.
This very low dropout is achieved thanks to a
second input voltage pin, named V
CONTROL
,
which is also responsable of the output power
stage driving.
The LD1580 is provided with an output voltage
remote sense pin which reduces dramatically any
suitable
in
decreases
at
output voltage variations that could occur due to
load changes.
On fixed voltage devices, the ADJ pin is still
available. A small capacitor on this pin helps to
improve transient response.
