3 Description
The TLV1117LV low-dropout (LDO) linear regulator is
a low input voltage version of the popular TLV1117
voltage regulator.
The TLV1117LV is an extremely low-power device
that consumes 500 times lower quiescent current
than traditional 1117 voltage regulators, making the
device designed for applications that mandate very
low standby current. The TLV1117LV LDO is also
stable with 0 mA of load current; there is no
minimum load requirement, making the device a
good choice for applications where the regulator must
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.
A precision band-gap and error amplifier provides
1.5% accuracy. A very high power-supply rejection
ratio (PSRR) enables use of the device for postregulation
after a switching regulator. Other valuable
features include low output noise and low-dropout
voltage.
The device is internally compensated to be stable with
0-Ω equivalent series resistance (ESR) capacitors.
These key advantages enable the use of costeffective,
small-size ceramic capacitors. Cost-effective
capacitors that have higher bias voltages and
temperature derating can also be used if desired.
The TLV1117LV is available in a SOT-223 package.
