Description

General part information

TLV117115 Series

The TLV1171 low-dropout (LDO) linear regulator is a low input voltage version of the popular 1117 voltage regulator.

The TLV1171 is an extremely low-power device that consumes 500x lower quiescent current than the traditional 1117 voltage regulator, making the TLV1171 suitable for applications that mandate very low standby current. The TLV1171 LDO 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 is required to power very small loads during standby in addition to large currents on the order of 1 A during normal operation. The TLV1171 offers excellent line and load transient performance, resulting in very small magnitude output voltage undershoots and overshoots 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 enables the device to be used for post-regulation after a switching regulator. Other valuable features include low output noise and low-dropout voltage.
