Frequently Asked Questions
What is the output current capability of the LM1084ISX-5.0/NOPB?
The LM1084ISX-5.0/NOPB is rated for a continuous output current of 5A, making it suitable for powering high-current loads such as DSP processors, FPGAs, and multi-device digital boards. Its on-chip current limiter protects the device during overload conditions without requiring external protection circuitry.
What is the dropout voltage of the LM1084ISX-5.0/NOPB?
The LM1084ISX-5.0/NOPB has a typical dropout voltage of 1.3V and a maximum of 1.5V at full 5A output current. This means the input supply must be at least 6.5V to maintain the regulated 5V output, which is ideal for designs using a 9V, 12V, or 15V input rail.
Is the LM1084ISX-5.0/NOPB RoHS compliant?
Yes, the LM1084ISX-5.0/NOPB is RoHS compliant and lead-free, as indicated by the NOPB suffix. The device uses tin-silver-copper solder terminations on its SOT-223 package and meets all EU RoHS Directive restrictions on hazardous substances in electronics.
Does the LM1084ISX-5.0/NOPB require external components?
The LM1084ISX-5.0/NOPB requires only a few external components — typically a 10 µF or greater output capacitor for stability and a small 0.1 µF input bypass capacitor. No external sense resistors or trim potentiometers are needed for the fixed 5V output version, simplifying PCB layout and bill of materials.
