1 / 25 page June 2007 Rev. 5 1/25 25 LD1585C series 5A Low dropout fast response positive voltage regulator adjustable and fixed Features ■ Typical dropout 1.2V ■ Fast transient response ■ Three terminal adjustable or fixed output voltage 1.5V 1.8V, 2.5V, 2.85V, 3.3V, 5V, 8V, 9V ■ Guaranteed output current up to 5A ■ Output tolerance ±1% at 25°C and ±2% in full temperature range ■ Internal power and thermal limit ■ Wide operating temperature range 0°C to 125°C ■ Package available: TO-220, D2PAK/A ■ Pinout compatibility with standard adjustable VREG 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.
