SBVS177 –APRIL 2012  
1-A, Positive Fixed-Voltage, Low-Dropout Regulator

FEATURES  
DESCRIPTION  
The TLV1171 low-dropout (LDO) linear regulator is a  
low input voltage version of the popular 1117 voltage  
regulator.  
2
•
•
Accuracy: 1.5% (typ)  
Low IQ: 100 μA (max)  
–
500x Lower Than Standard 1117 Devices  
VIN: 2.0 V to 5.5 V  
Absolute Maximum VIN: 6.0 V  
The TLV1171 is an extremely low-power device that  
consumes 500x lower quiescent current than the  
traditional 1117 voltage regulator, making the  
TLV1171 suitable for applications that mandate very  
low standby current. The TLV1171 LDO is also stable  
with 0 mA of load current; there is no minimum load  
requirement, making the device an ideal choice for  
applications where the regulator is required to power  
very small loads during standby in addition to large  
currents on the order of 1 A during normal operation.  
The TLV1171 offers excellent line and load transient  
performance, resulting in very small magnitude output  
voltage undershoots and overshoots when the load  
current requirement changes from less than 1 mA to  
more than 500 mA.

Stable with 0-mA Output Current  
Low Dropout: 455 mV at 1 A for VOUT = 3.3 V  
High PSRR: 65 dB at 1 kHz  
Minimum Ensured Current Limit: 1.1 A  
Stable with Cost-Effective Ceramic Capacitors:

Temperature Range: –40°C to +125°C  
Thermal Shutdown and Overcurrent Protection  
Available Package: SOT223  
–
See the Package Option Addendum at the  
end of this document for a complete list of  
available voltage options.  
A precision band gap and error amplifier provides  
1.5% accuracy. A very high power-supply rejection  
ratio enables the device to be used for post-  
regulation after a switching regulator. Other valuable  
features include low output noise and low-dropout  
voltage.  
APPLICATIONS  
•

•
•
•
Set Top Boxes  
The device is internally compensated to be stable  
with 0-Ω equivalent series resistance (ESR)  
capacitors. These key advantages enable the use of  
cost-effective, small-size ceramic capacitors. Cost-  
effective capacitors that have higher bias voltages  
and temperature derating can also be used if desired.
