Products DESCRIPTION
The TPS781 family of low-dropout (LDO) regulators
offer the benefits of ultralow power (IQ = 1ВµA),
miniaturized packaging (2Г—2 SON-6), and selectable
dual-level output voltage levels. An adjustable version
is also available, but does not have the capability to
shift voltage levels.
