3 Description
The TPS727 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 band-gap and error
amplifier provides overall 2% accuracy over load, line,
and temperature extremes. The TPS727 family is
available in 1.5-mm × 1.5-mm SON and wafer chip-
scale (WCSP) packages that make the devices ideal
for handheld applications. This family of devices is
fully specified over a temperature range of T_J =
–40°C to +125°C.
