Description
The LD1585C is a low drop voltage regulator able
to provide up to 5 A of output current. Dropout is
guaranteed at a maximum of 1.4 V at the
maximum output current, decreasing at lower
loads. The device has been improved to be
utilized in low voltage applications where transient
response and minimum input voltage are critical.
The most important feature of the device consist
in lower dropout voltage and very fast transient
response. A 2.85 V output version is suitable for
SCSI-2 active termination. Unlike PNP regulators,
where a part of the output current is wasted as
quiescent current, the LD1585C quiescent current
flows into the load, so increase efficiency. Only a
10 µF minimum capacitor is need for stability.
TO-220
The device is supplied in TO-220. On chip
trimming allows the regulator to reach a very tight
output voltage tolerance, within ± 1 % at 25 °C.
