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 TJ =

–40°C to +125°C.
