Manufacturer Part Number
ld1585cd2t90
Description
5a Low Dropout Fast Response Positive Voltage Regulator Adjustable And Fixed
Manufacturer
STMicroelectronics
Datasheet
POSITIVE VOLTAGE REGULATOR ADJUSTABLE AND FIXED
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

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.
