It accepts an input from 2.15 V up to 6.5 V and can be set to any output voltage between a fixed 0.8 V minimum and 5 V maximum. What sets this part apart is its dual current rating: 50 mA on one output path and 500 mA on the other, both from the same regulator — a configuration that suits designs needing a low-current always-on rail plus a higher-current switched rail from one converter. The 2 MHz switching frequency keeps external inductor and capacitor values small, which is the main reason you see this part in space-constrained portable or battery-powered gear. The synchronous rectifier is integrated, so no external Schottky diode is needed.
Package and temperature — what drives the board
The package is a 9-ball WLCSP measuring 1.87 x 1.65 mm.
It is also ROHS3 compliant, which clears the EU regulatory gate for new designs. From a procurement standpoint, this part is in the normal production cycle — no allocation signals or extended lead-time flags typical of shortage-driven parts.
What the dual current rating means for your BOM
The 50 mA and 500 mA ratings are for a single-output regulator configured by the feedback network.
