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.
