FEATURES  
DESCRIPTION  
234  
2% Accuracy  
The TLV712xx series of low-dropout linear regulators  
(LDOs) are low quiescent current devices with  
excellent line and load transient performance. These  
devices provide sub-bandgap output voltages; that is,  
output voltages less than 1.2 V all the way down to  
0.7 V. Therefore, these LDOs can be used to power  
processors with operating voltages less than 1.2 V.  
These LDOs are designed for power-sensitive  
applications. A precision bandgap and error amplifier  
provides overall 2% accuracy. Low output noise, very  
high power-supply rejection ratio (PSRR), and  
low-dropout voltage make this series of devices ideal  
for a wide selection of battery-operated handheld  
equipment. All device versions have thermal  
shutdown and current limit for safety.  
Low IQ: 35 mA  
Fixed-Output Voltage Combinations Possible  
from 0.7 V to 1.15 V(1)  
High PSRR: 68 dB at 1 kHz  
Stable with Effective Capacitance of 0.1 mF(2)  
Thermal Shutdown and Overcurrent Protection  
Packages: SOT23-5, 1,5-mm × 1,5-mm SON-6  
(1)  
For output voltage of 1.2 V and higher, see the TLV702 family  
of devices.  
(2)  
See the Input and Output Capacitor Requirements in the  
Application Information section.  
APPLICATIONS  
Furthermore, these devices are stable with an  
effective output capacitance of only 0.1 mF. This  
feature enables the use of cost-effective capacitors  
that have higher bias voltages and temperature  
derating. The devices regulate to specified accuracy  
with no output load.  
Wireless Handsets  
Smart Phones, PDAs  
MP3 Players  
ZigBee® Networks  
Bluetooth® Devices  
The TLV712xxP series also provides an active  
pull-down circuit to quickly discharge the outputs.  
Li-Ion Operated Handheld Products  
WLAN and Other PC Add-on Cards  
The TLV712xx series of LDO linear regulators are  
available in SOT23-5 and 1,5-mm x 1,5-mm SON-6  
packages.
