TPS72730DSER

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 chipscale (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.
