TPS717-Q1  
SLVSBM4C –SEPTEMBER 2012–REVISED JANUARY 2016  
TPS717-Q1  
Low-Noise, High-Bandwidth PSRR, Low-Dropout, 150-mA Linear Regulator  
1 Features  
3 Description  
The TPS717-Q1 family of low-dropout (LDO), low-  
power linear regulators offers very high power-supply  
rejection (PSRR) and maintains very low 45-μA  
ground current in an ultra-small, five-pin SOT  
package. The family uses an advanced BiCMOS  
process and a PMOSFET pass device to achieve fast  
start-up, very low noise, excellent transient response,  
and excellent PSRR performance. The TPS717-Q1 is  
stable with a 1-μF ceramic output capacitor and uses  
a precision voltage reference and feedback loop to  
achieve a worst-case accuracy of 3% over all load,  
line, process, and temperature variations. The device  
family is fully specified from TJ, TA = –40°C to 125°C  
and is offered in a small SOT (SC70-5) package, a  
2-mm × 2-mm WSON-6 package with a thermal pad,  
and a 1.5-mm × 1.5-mm WSON-6 package, which  
are ideal for small form-factor portable equipment  
(such as wireless handsets and PDAs). The TPS717-  
Q1 family of LDOs is qualified for AEC-Q100 grade 1.
