Frequently Asked Questions
What is the output current capability of the LM1084ISX-ADJ/NOPB?
The LM1084ISX-ADJ/NOPB can supply up to 5 A of continuous output current, making it suitable for powering high-current loads such as FPGA core rails, processor power supplies, and motor pre-drivers.
What is the dropout voltage of the LM1084ISX-ADJ/NOPB?
The device has a typical dropout voltage of 1.3 V and a maximum of 1.5 V at full 5 A load, allowing it to maintain regulation with the input supply only slightly above the desired output voltage.
How is the output voltage set on the LM1084ISX-ADJ/NOPB?
The adjustable output version uses two external resistors connected to the ADJ pin and output to set any voltage from approximately 1.25 V up to the input supply minus the dropout voltage, following the standard LDO divider formula.
Is the LM1084ISX-ADJ/NOPB RoHS compliant?
Yes, the NOPB (No Lead, Pb-Free) suffix confirms that this device is fully RoHS compliant and manufactured without lead, making it suitable for environmentally regulated markets worldwide.
