TI TLV1171 Low-Dropout Linear Regulator

Texas Instruments TLV1171 low-dropout (LDO) linear regulator is a low input voltage version of 1117 voltage regulator. TI TLV1171 LDO is an extremely low-power device that consumes 500x lower quiescent current than the traditional 1117 voltage regulator, making it suitable for applications that mandate very low standby current. TLV1171 LDO is also stable with 0mA of load current. The device has no minimum load requirement, making it an ideal choice for applications in which the regulator is required to power very small loads during standby in addition to large currents on the order of 1A during normal operation. 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 1mA to more than 500mA.

TI TLV117125EVM-097 Evaluation Module demonstrates the proper operation of the TLV1117125 1A, Positive Fixed Voltage, Low-Dropout Linear Regulator. The EVM is a fully assembled, stand alone evaluation module.
