DESCRIPTION
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.
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.
The TLV712xxP series also provides an active
pull-down circuit to quickly discharge the outputs.
The TLV712xx series of LDO linear regulators are
available in SOT23-5 and 1,5-mm x 1,5-mm SON-6
packages.
