DESCRIPTION
The TLV700xx/TLV701xx 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.
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 TLV700xx series of LDOs are available in
1,5-mm x 1,5-mm SON-6, TSOT23-5, and SC-70
packages. The TLV701xx series of LDOs are
available in a 1,5-mm x 1,5-mm SON-6 package.
