SBVS128E –JUNE 2009–REVISED SEPTEMBER 2014  
TPS727xx 250-mA, Ultralow IQ, Fast Transient Response,  
RF Low-Dropout Linear Regulator  
1 Features  
3 Description  
The TPS727xx 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

A
precision band-gap and error  
Ultralow IQ: 7.9 μA  
amplifier provides overall 2% accuracy over load, line,  
and temperature extremes. The TPS727xx 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.  
Excellent Load Transient Performance:±50 mV for  
200 mA Loading and Unloading Transient
