FEATURES  
DESCRIPTION  
•
Dual 250 mA High-Performance RF LDOs  
The TPS712xx family of low-dropout (LDO) voltage  
regulators is tailored to noise-sensitive and RF  
applications. These products feature dual 250 mA  
LDOs with ultralow noise, high power-supply rejection  
ratio (PSRR), and fast transient and start-up  
response. Each regulator output is stable with  
low-cost 2.2 mF ceramic output capacitors and  
features very low dropout voltages (125 mV typical at  
250 mA). Each regulator achieves fast start-up times  
(approximately 60 ms with a 0.001 mF bypass  
capacitor) while consuming very low quiescent  
current (300 mA typical with both outputs enabled).  
When the device is placed in standby mode, the  
supply current is reduced to less than 0.3 mA typical.  
Each regulator exhibits approximately 32 mVrms of  
output voltage noise with VOUT = 2.8 V and a 0.01 mF  
noise reduction (NR) capacitor. Applications with  
analog components that are noise-sensitive, such as  
portable RF electronics, will benefit from high PSRR,  
low noise, and fast line and load transient features.  
The TPS712 family is offered in a thin 3mm x 3mm  
SON package and is fully specified from -40°C to  
+125°C (TJ).
