Texas Instruments TPS727 Ultra-Low Iq LDO Linear Regulators
Texas Instruments TPS727 Ultra-Low Iq Low-Dropout Linear Regulators are ultra-low 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 an overall 2% accuracy over load, line, and temperature extremes. The Texas Instruments TPS727 family is available in 1.5mm × 1.5mm 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.
