UVLO: Under Voltage Lock Out
A number of protection functions are
included for increased reliability
CMOS utilized at output stage
reduces the number of external parts
CMOS processes adopted at the output
stage (Pch/Nch) eliminate the need for an
external capacitor normally required with
NMOS configurations
Improved response to load
changes, along with greater
control accuracy, result in
quick startup - even during
low speeds
