3 Description
The TLV717P series of low-dropout (LDO) linear
regulators are low quiescent current LDOs with
excellent line and load transient performance and are
designed for power-sensitive applications. These
devices provide a typical accuracy of 0.5%.
The TLV717P series offer current foldback that
throttles down the output current with a decrease in
load resistance. The typical value at which current
foldback initiates is 350 mA; the typical value of the
output short current limit value is 40 mA.
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 TLV717P series is available in a 1-mm × 1-mm
DQN package that makes them ideal for hand-held
applications. The TLV717P provides an active
pulldown circuit to quickly discharge output loads.
