3 Description
The TLV1117LV series of low-dropout (LDO) linear
regulators 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 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 the device an
ideal 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 bandgap and error amplifier provides
1.5% accuracy. A very high power-supply rejection
ratio (PSRR) enables use of the device for post-
regulation 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
cost-effective, small-size ceramic capacitors. Cost-
effective capacitors that have higher bias voltages
and temperature derating can also be used if desired.
The TLV1117LV series is available in a SOT-223
package.
