The switch integrates fixed current limiting, over-temperature shutdown, and undervoltage lockout (UVLO). The Auto Restart feature re-enables the output after a fault condition clears, which simplifies recovery in systems that cannot tolerate a latched-off state.
The SC-70-5 (SOT-353) footprint is compact — 2.0 mm × 2.1 mm — and the 0.65 mm pin pitch breaks out easily on two-layer boards.
At 3.3 V input and 100 mA load, the 400 mOhm typical Rds(on) yields a voltage drop of about 40 mV.
The device is listed as RoHS compliant per the manufacturer's standard green packaging. The SC-70-5 package is lead-free and compatible with lead-free reflow profiles.
