The LD1580 is a very low dropout positive linear
voltage regulator particularly suitable in
applications requiring output currents up to 7 A.
The LD1580 typical dropout voltage is 400 mV at
7 A while it decreases at lighter loads.
This very low dropout is achieved thanks to a
second input voltage pin, named VCONTROL,
which is also responsible of the output power
stage driving.
The LD1580 is provided with an output voltage
remote sense pin which reduces dramatically any
output voltage variations that could occur due to
load changes.
The ADJ pin is still available. A small capacitor on
this pin helps to improve transient response.
The LD1580 also features a built-in output current
limit function and a thermal shutdown protection
with hysteresis which prevents from excessive
power dissipation in case of insufficient
heatsinking. On chip trimming allows the regulator
to reach a very tight output voltage tolerance,
within ± 2 % at the maximum output current and
over the full temperature range.
