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.

  • Very Low Dropout:
    • 65 mV Typical at 100 mA
    • 130 mV Typical at 200 mA
    • 163 mV Typical at 250 mA
  • 2% Accuracy Over Load, Line, Temperature
  • Ultralow IQ: 7.9 µA
  • Excellent Load Transient Performance:±50 mV for
    200 mA Loading and Unloading Transient
  • Available in Fixed-Output Voltages From 0.9 V to
    5 V Using Innovative Factory EEPROM Programming
  • High PSRR: 70 dB at 1 kHz
  • Stable with a 1.0-µF Ceramic Capacitor
  • Thermal Shutdown and Overcurrent Protection
  • Available in 4-Ball, 0.4-mm Pitch Wafer-Level
    Chip Scale and 1.5-mm × 1.5-mm SON Packages
