Features, Applications
5A LOW DROPOUT FAST RESPONSE POSITIVE VOLTAGE REGULATOR ADJUSTABLE AND FIXED

TYPICAL DROPOUT 1.2V FAST TRANSIENT RESPONSE THREE TERMINAL ADJUSTABLE OR FIXED OUTPUT VOLTAGE 9V, 12V. GUARANTEED OUTPUT CURRENT TO 5A OUPUT TOLERANCE AT 25°C AND ±2% IN FULL TEMPERATURE RANGE INTERNAL POWER AND THERMAL LIMIT WIDE OPERATING TEMPERATURE RANGE TO 125°C PACKAGE AVAILABLE D2PAK, D2PAK/A PINOUT COMPATIBILITY WITH STANDARD ADJUSTABLE VREG

DESCRIPTION The is a LOW DROP Voltage Regulator able to provide 5A of Output Current. Dropout is guaranteed at a maximum 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 SCHEMATIC DIAGRAM

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 10”F minimum capacitor is need for stability. The device is supplied TO-220, D2PAK and D2PAK/A. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within at 25°C.
