DESCRIPTION
The TPS727xx family of low-dropout (LDO) linear
regulators are ultralow quiescent current LDOs with
excellent line and ultra-fast load transient
performance and are designed for power-sensitive
applications. The LDO output voltage level is preset
by the use of innovative factory EEPROM
programming. A precision bandgap and error
amplifier provides overall 2% accuracy over load, line,
and temperature extremes. The TPS727xx family is
available in 1,5mm x 1,5mm SON and wafer
chip-scale (WCSP) packages that make it ideal for
handheld applications. This family of devices is fully
specified over a temperature range of T_J = –40°C to
+125°C.
