Regulator leaves the 5V rail
The LTC3026 is a 1.5A very low dropout linear regulator with input voltage capability down to 1.14V.
Linear Technology has released the LTC3026, a 1.5A very low dropout (VLDO) linear regulator with input voltage capability down to 1.14V Featuring adjustable ultra-low-output-voltage operation from 0.4 to 2.6V, it also maintains extremely low dropout voltage of only 100mV while delivering up to 1.5A of output current

Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
To allow operation at low input voltages, the LTC3026 includes an integrated boost convertor that provides the necessary headroom for the internal LDO circuitry.
This feature ensures users the flexibility of lower input voltage capability if an external 5V rail is not available in the system.
The LTC3026's high supply rejection capability enables it to be a highly effective postregulator for switching power supplies.
Other key applications include high-efficiency linear regulation from low input voltage 2.5/1.8/1.5V rails, plus powering low-voltage, high-current digital ICs such as microcontrollers, microprocessors, PLDs/FPGAs and DSPs.
The LTC3026 regulator optimises stability and transient response with low ESR, ceramic output capacitors as small as 10uF.
Its internal protection circuitry includes soft-start, current limiting, thermal limiting, and reverse-current protection.
Its shutdown disconnect feature disconnects both VIN and VBST from the output load in shutdown.
The LTC3026EDD and LTC3026EMSE are available from stock in the 10-lead DFN (3 x 3 x 0.75mm) package and 10-lead MSOP package, respectively.
Both packages offer thermally efficient, highly compact solution footprints.
