3 Description
The TLV702 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.
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.
The TLV702P series also provides an active pulldown
circuit to quickly discharge the outputs.
The TLV702 series of LDO linear regulators are
available in SOT23-5 and 1.5-mm × 1.5-mm SON-6
packages.
