The TLV1117LV series of low-dropout (LDO) linear
regulators is a low input voltage version of the
popular 1117 voltage regulator.
The TLV1117LV is an extremely low-power device
that consumes 500 times lower quiescent current
than traditional 1117 voltage regulators, making it
suitable for applications that mandate very low
standby current. The TLV1117LV family of LDOs is
also stable with 0 mA of load current; there is no
minimum load requirement, making it an ideal choice
for applications where the regulator is required to
power very small loads during standby in addition to
large currents on the order of 1 A during normal
operation. The TLV1117LV offers excellent line and
load transient performance, resulting in very small
magnitude undershoots and overshoots of output
voltage when the load current requirement changes
from less than 1 mA to more than 500 mA.

APPLICATIONS
A precision bandgap and error amplifier provides
1.5% accuracy. A very high power-supply rejection
ratio enables usage of the device for post-regulation
after a switching regulator. Other valuable features
include low output noise and low-dropout voltage.

capacitors. These key advantages enable the use of
cost-effective, small-size ceramic capacitors.
Cost-effective capacitors that have higher bias
voltages and temperature derating can also be used
if desired.
