Description
Description for the TLV1117LV 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 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 is available in a SOT-223 package. Features for the TLV1117LV Typical accuracy: 1.5% Low IQ: 100 µA (maximum) 500 times lower than standard 1117 devices VIN: 2 V to 5.5 V Absolute maximum VIN: 6 V Stable With 0-mA output current Low dropout: 455 mV at 1 A for VOUT = 3.3 V High PSRR: 65 dB at 1 kHz Minimum specified current limit: 1.1 A Stable with cost-effective ceramic capacitors: With 0-Ω ESR Temperature range: –40°C to +125°C Thermal shutdown and overcurrent protection For drop-in replacement with upgraded functionality, see the TLV761 Available in a SOT-223 package See the Mechanical, Packaging, and Orderable Information section at the end of this document for a complete list of available voltage options.
