LD1585CXX Datasheet | STMicroelectronics

Features - - Typical dropout 1.2 V Fast transient response up to 5 A - Three terminal adjustable .. - Guaranteed output current - - - - - 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 Pinout patibility with standard adjustable VREG The device is supplied in TO-220. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 1 % at 25 °C. TO-220 Description The LD1585C is a low drop voltage regulator able to provide up to 5 A of output current. Dropout is guaranteed at a maximum of 1.4 V 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 2.85 V 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 µF minimum capacitor is need for stability. Table 1. Device summary Part number LD1585CXX Order code LD1585CV Output voltage ADJ July 2008 Rev 8 1/15 .st. 15 Contents Contents 1 2 3 4 ..
