Product Summary

The LTC3026EMSE is a very low dropout (VLDOTM) linear regulator that can operate at input voltages down to 1.14V. The LTC3026EMSE is capable of supplying 1.5A of output current with a typical dropout voltage of only 100mV. To allow operation at low input voltages the LTC3026EMSE includes a boost converter that provides the necessary headroom for the internal LDO circuitry. Applications of the LTC3026EMSE include: high eficiency linear regulator, post regulator for switching supplies and microprocessor supply.
