• Very Low Dropout:
The TPS727xx family of low-dropout (LDO) linear
regulators are ultralow quiescent current LDOs with
– 65mV Typical at 100mA
excellent line and ultra-fast load transient
– 130mV Typical at 200mA
performance and are designed for power-sensitive
– 163mV Typical at 250mA
applications. The LDO output voltage level is preset
• 2% Accuracy Over Load/Line/Temperature by the use of innovative factory EEPROM
programming. A precision bandgap and error
• Ultralow I
Q
: 7.9mA
amplifier provides overall 2% accuracy over load, line,
• Excellent Load Transient Performance:±50mV
and temperature extremes. The TPS727xx family is
for 200mA Loading/Unloading Transient
available in 1,5mm x 1,5mm SON and wafer
