The TPS720xx uses a precision voltage reference
and feedback loop to achieve overall accuracy of 2%
over load, line, process, and temperature extremes.
An ultra-small wafer chip-scale package (WCSP)
makes the TPS720xx ideal for handheld applications.
The TPS720xx is also available in a SON-8 package.
