Descripción de TPS728
The TPS728xx series of low-dropout linear regulators (LDOs), with a selectable dual-voltage level output, is designed specially for applications that require two levels of output voltage regulation. Programming fuses and memory cards, reducing leakage effects, and conserving power in nanometric processes are some application examples.
The VSET pin is used to select one of two output voltage levels preset through innovative factory EEPROM programming. A precision bandgap and error amplifier provides an overall 3% accuracy over load, line, and temperature extremes.
Ultra-small wafer chip scale (WCSP) and 2mm x 2mm SON packages make the TPS728xx series ideal for handheld applications.
This family of devices is fully specified over a temperature range of TJ = -40°C to +125°C.
