Product Overview

The TLV1117LV33DCYR is a low-dropout (LDO) Linear Voltage Regulator, low input voltage version of the popular TLV1117 voltage regulator. It 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 0mA 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 1A during normal operation. It 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 1mA to more than 500mA.
