A dual-supply power solution typically improves conversion efficiency over a single-supply solution because the higher VBIAS supply powers the part, and the lower VIN supply delivers current to the load. The power dissipated in the device is thereby reduced.The ADP130AUJZ-0.8-R7 is optimized for stable operation with small 1 μF ceramic output capacitors. The ADP130AUJZ-0.8-R7 delivers good transient performance with minimal board area.
The ADP130AUJZ-0.8-R7 is available in fixed output voltages ranging from : 0.80 V to 3.0 V.
The ADP130AUJZ-0.8-R7 has a typical internal soft start time of 200 μs. Short-circuit protection and thermal overload protection circuits prevent damage in adverse conditions. The ADP130AUJZ-0.8-R7 is available in a tiny 5-lead TSOT package for the smallest footprint solution to meet a variety of portable power applications.
