Description

The LD1585C is a LOW DROP Voltage Regulator

able to provide up to 5A of Output Current.

Dropout is guaranteed at a maximum of 1.4V 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 2.85V 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

10µF minimum capacitor is need for stability.

The device is supplied in TO-220, D2PAK and

D2PAK/A. On chip trimming allows the regulator to

reach a very tight output voltage tolerance, within

±1% at 25°C.
