TLV1171 Low-Dropout Regulator

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 st.
