ULTRALOW-NOISE, HIGH PSRR, FAST RF 1-A  
LOW-DROPOUT LINEAR REGULATORS  
FEATURES  
DESCRIPTION  
•
1-A Low-Dropout Regulator With Enable  
The TPS796xx family of low-dropout (LDO)  
low-power linear voltage regulators features high  
power supply rejection ratio (PSRR), ultralow-noise,  
fast start-up, and excellent line and load transient  
responses in small outline, 3 x 3 SON, SOT223-6,  
and 5-pin DDPAK packages. Each device in the  
family is stable with a small 1-µF ceramic capacitor  
on the output. The family uses an advanced, pro-  
prietary BiCMOS fabrication process to yield ex-  
tremely low dropout voltages (e.g., 250 mV at 1 A).  
•
Available in 1.8-V, 2.5-V, 2.8-V, 3-V, 3.3-V, and  
Adjustable (1.2-V to 5.5-V)  
•
•
•
•
•
•
High PSRR (53 dB at 10 kHz)  
Ultralow-Noise (40 µVRMS, TPS79630)  
Fast Start-Up Time (50 µs)  
Stable With a 1-µF Ceramic Capacitor  
Excellent Load/Line Transient Response  
Each device achieves  
fast  
start-up times  
Very Low Dropout Voltage (250 mV at Full  
Load, TPS79630)  
(approximately 50 µs with a 0.001-µF bypass capaci-  
tor) while consuming very low quiescent current  
(265 µA typical). Moreover, when the device is placed  
in standby mode, the supply current is reduced to  
less than 1 µA. The TPS79630 exhibits approximately  
40 µVRMS of output voltage noise at 3.0-V output, with  
a 0.1-µF bypass capacitor. Applications with analog  
components that are noise sensitive, such as portable  
RF electronics, benefit from the high PSRR, low  
noise features, and the fast response time.
