LM1086ISX-ADJ Adjustable Voltage Regulator with 5A Output Current, 2.5V to 20V Input Range, and 1.25V Adjustable Output

Function: The LM1086ISX-ADJ is an adjustable positive linear voltage regulator belonging to the LM1086 family, designed for medium-current power supply applications. It operates with an input voltage range of 2.5V to 20V and provides an adjustable output voltage from 1.25V up to (V_IN - 1.5V), enabling flexible power configuration for various loads. The device delivers a maximum output current of 5A (with proper heatsinking) and features excellent line regulation (typical 0.05%/V) and load regulation (typical 0.15% at full load), ensuring stable output voltage against input voltage and load variations. It integrates built-in thermal shutdown and current limit protection circuits to prevent damage from overheating or short-circuit conditions, enhancing system reliability. The LM1086ISX-ADJ is packaged in a surface-mount TO-263-5 (D2PAK) package, offering good thermal dissipation and compatibility with automated assembly processes.
