Device summary

Part number

LD1585CXX

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 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.

TO-220

-O

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.
