It operates from a 2.3 V to 5.5 V input supply, covering common 5 V rails used in portable devices, USB peripherals, and industrial sensor interfaces. The part is housed in a 5-pin SC-70-5 package, making it suitable for space-constrained PCB layouts where a discrete resistor-fuse solution would take more area. ## 50 mA current limit — sizing the load The 50 mA output rating is the fixed current limit. This is not adjustable — the part is intended for loads that draw up to 50 mA steady-state, with headroom for inrush. Typical applications include USB port power limiting, where a 50 mA limit protects a host port from a shorted peripheral, or as a current limiter on a sensor supply rail in an industrial I/O module. If your load peaks above 50 mA, this part will fold back or latch off depending on the variant; the MAX4785EXK+T is the auto-retry version. Verify your load's peak current stays under the limit to avoid nuisance tripping. ## Lifecycle and compliance It is RoHS3 compliant, so it meets current EU and global environmental requirements for new product introductions.","metaTitle":"MAX4785EXK+T Current Limiting IC, 50 mA, SC-70-5","metaDescription":"MAX4785EXK+T current limiting IC from Maxim Integrated. 50 mA output, 2.3 V to 5.5 V input, SC-70-5 package, -40°C to 85°C.
