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.
