FEATURES
DESCRIPTION
The TLV700xx 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 most
battery-operated handheld equipment. All device
versions have thermal shutdown and current limit for
safety.

43 mV at IOUT = 50 mA, VOUT = 2.8 V
85 mV at IOUT = 100 mA, VOUT = 2.8 V
175 mV at IOUT = 200 mA, VOUT = 2.35 V

•
Low IQ: 31 μA
Available in Fixed-Output Voltages from 1.2 V
to 4.8 V
•
•
•
•
High PSRR: 68 dB at 1 kHz
Stable with Effective Capacitance of 0.1 μF(1)
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.
Thermal Shutdown and Overcurrent Protection
Available in 1,5-mm × 1,5-mm SON-6, SOT23-5,
and SC-70 Packages
