FEATURES  
DESCRIPTION  
234  
•
Very Low Dropout:  
The TLV702xx series of low-dropout (LDO) linear  
regulators are low quiescent current devices with  
excellent line and load transient performance. 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.  
–
–
–
37 mV at IOUT = 50 mA, VOUT = 2.8 V  
75 mV at IOUT = 100 mA, VOUT = 2.8 V  
220mV at IOUT = 300 mA, VOUT = 2.8 V  
•
2% Accuracy  
•
•
Low IQ: 35 μA  
Fixed-Output Voltage Combinations Possible  
from 1.2 V to 4.8 V  
•
•
•
High PSRR: 68 dB at 1 kHz  
Stable with Effective Capacitance of 0.1 μF(1)  
Thermal Shutdown and Overcurrent Protection  
Packages: SOT23-5 and 1,5mm × 1,5mm SON-6  
Furthermore, these devices are stable with an  
effective output capacitance of only 0.1 μF. 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.  
•
(1)  
See the Input and Output Capacitor Requirements in the  
Application Information section.  
The TLV702xxP series also provides an active  
pulldown circuit to quickly discharge the outputs.
